Mini hard drive USB flash drive homemade on the computer. Can a hard drive be used as a USB flash drive
In this article, we will show you how to make sure that USBflash drive or SDthe card was detected in the Windows system like a normal local hard drive... You are probably asking, why is this necessary? The fact is that Windows by default defines USB flash drives and memory cards as removable drives that cannot be divided into several partitions using Windows standards. And even if you split the flash drive into two or more partitions using third-party utilities (in the same Linux), then only the first of them will be available in the Windows operating system (by the way, a built-in one appeared in Windows 10 1703). Those. Windows supports normal work with multipartitions only for HDD disks, which are defined in the system as local (i.e. non-removable).
RMB bits and USB sticks
Windows operating systems recognize USB flash drives as removable / removable devices due to the presence of a special bit descriptor on each device RMB(removablemediabit) ... If, when polling a connected device through the StorageDeviceProperty function, the system determines that RMB = 1, it concludes that the connected device is a removable storage device. Thus, in order from the system's point of view to convert a USB-flex to a hard disk, it is enough to modify this descriptor. This can be done directly (which is quite risky due to differences in hardware implementations of specific devices, and it is not always possible), or indirectly, by replacing the USB device's response using a special driver that allows filtering information in the device's response.
Advice... Some manufacturers produce special utilities for flashing the controller of their flash drives. First of all, try to find such a utility and / or firmware on the manufacturer's website. This is the most correct way. If such a utility is not found, follow the recommendations from this article.
Connect a USB flash drive to any free port on your computer, then open the Disk Management Manager ( diskmgmt.msc) and make sure that its type is defined in the system as Removable(Removable device) .
Also, the device type can be viewed on the Volumes tab in the disk properties (as we can see here Type: Removable). 
Or using the diskpart command:
List volume
In this article, we will consider two ways to change the RMB bit on a USB flash drive - using the Hitachi filter driver (changes are made only at the driver level of a specific computer) and changing the bit in the controller firmware using the BootIt utility from Lexar (a more universal method, but there is a number of restrictions and does not apply to all models of flash drives and SD cards). Although both of these methods are quite old and I initially tested them on Windows 7, they continue to be relevant and work equally well on modern Windows 10.
Lexar BootIt Utility
Recently I came across a rather interesting utility - LexarBootIt... It is a free portable program that can change the RMB of a removable storage device to a fixed USB device (or vice versa). Despite the fact that the Lexar BootIt utility is designed for Lexar devices (Micron, Crucial), it can work with flash drives from other manufacturers. BootIt utility supports all versions of Windows from Windows XP to Windows 10.
Important... The utility is guaranteed to work for Lexar drives. Judging by the reviews, the "Flip removable bit" function does not work on fast USB 3.0 flash drives. In addition, when you reflash the controller, you void the warranty for the USB flash drive and can make it inoperable.
You can download BootIt on the Lexar website (lexar_usb_tool) or from our website ().
- Run BootIt.exe as administrator
- In the list of devices, select your USB flash drive
- Click on the button Flip Removable Bit
- Save your changes by clicking OK.
Reconnect the device and use Device Manager to verify that it has changed from Removable to Basic.
If the BootIt utility did not help to change the RMB bit on the removable drive, try the following method based on the Hitachi Microdrive filter driver
Filter driver for flash drives Hitachi Microdrive
In order for a USB flash drive or SD card to be recognized in the system as a hard drive, we need a special filter driver that allows us to modify the data passed through the system stack of the current device driver. We will use Hitachi's USB flash drive filter driver ( Hitachi Microdrive driver), which at the OS driver level allows you to change the type of flash drive from removable to fixed (USB-ZIP -> USB-HDD). By using this driver, you can hide from the system that the connected device is removable. As a result, the system will consider that it is working with a regular hard disk, which can be divided into partitions that will be simultaneously available in the system.
Hitachi Microdrive Driver Archives:
- 32 bit systems - (3.0 Kb)
- Hitachi Microdrive version for 64 bit systems - (3.8 Kb)
It is necessary to download the driver version for your system in accordance with its bitness. Both archives have the same structure and consist of two files:
- cfadisk.inf- installation file, with driver settings
- cfadisk.sys- Hitachi driver file
The next step is to identify the device code of our flash drive. To do this, in the properties of the disk on the tab Details in parameter Device Instance Path select and copy ( Ctrl + C) device instance code. 
In our example, this will be:
USBSTOR \ Disk & Ven_Linux & Prod_File-CD_Gadget & Rev_0000 \ 0123456789ABCDEF & 0
Suppose we are planning to install a driver on 64 bit system... Using any test editor, open the file for editing cfadisk.inf... We are interested in the sections cfadisk_device and cfadisk_device.NTamd64.
% Microdrive_devdesc% = cfadisk_install, IDE \ DiskTS64GCF400 ______________________________ 20101008% Microdrive_devdesc% = cfadisk_install, IDE \ DiskTS64GCF400 ______________________________ 20101008
We change the value of DiskTS64GCF400______________________________20101008 to the code of our device.
Important! In the code of the device instance, it is necessary to discard the part after the second "\" (in our example, discard 0123456789ABCDEF & 0).
We get:
% Microdrive_devdesc% = cfadisk_install, IDE \ USBSTOR \ Disk & Ven_Linux & Prod_File-CD_Gadget & Rev_0000% Microdrive_devdesc% = cfadisk_install, IDE \ USBSTOR \ Disk & Ven_Linux & Prod_File-CD_Gadget & Rev_0000
We save the file.
If the driver is installed on a 32 bit system, you need to download the recommended archive, unpack it and open the cfadisk.inf file for editing. Find the section :
% Microdrive_devdesc% = cfadisk_install, USBSTOR \ Disk & Ven_LEXAR & Prod_JD_LIGHTNING_II & Rev_1100% Microdrive_devdesc% = cfadisk_install, USBSTOR \ Disk & Ven_JetFlash & Prod_TS1GJF110 & cf.
Then we will change the data in the last line by specifying the code of the instance of our flash drive, i.e. in our example we get:
% Microdrive_devdesc% = cfadisk_install, USBSTOR \ Disk & Ven_LEXAR & Prod_JD_LIGHTNING_II & Rev_1100% Microdrive_devdesc% = cfadisk_install, USBSTOR \ Disk & Ven_JetFlash & Prod_TS1GJF110 & Rev_0dev% Microd_TS1GJF110 & Rev_0dev% Microdinstall
Advice... If you want the USB flash drive to be displayed with a specific name in the device manager, you need to edit the value of the Microdrive_devdesc variable, for example:
Microdrive_devdesc = "Transcend 64GB DIY SSD"
Installing the Hitachi Microdrive driver instead of the native USB drive driver
It remains to replace the driver used by the USB flash drive.
Important! If the Hitachi Microdrive USB driver is installed on a 64-bit system, then there is no digital signature for this driver, you have to either.
Open the Drivers tab and click the button Update Drivers. 
Specify the folder to the directory into which the downloaded archive with the Hitachi driver is unpacked: 
Let's choose a new driver. 
We ignore the warning about the missing digital signature of the driver. 
Advice... In Windows 10 and Windows 8, when installing the driver, the following error appears:
Windows found drivers for this device, but an error occurred while trying to install these drivers.
Hitachi Microdrive
Third party inf does not contain signature information
To disable verification of the digital signature of the driver, run the commands:
bcdedit.exe / set nointegritychecks ON
bcdedit.exe / set TESTSIGNING ON
Restart your computer and try to install the driver again.
It remains to restart the computer and, opening the disk manager, make sure that your flash drive has begun to be defined as a regular hard drive ( Type: Basic), and the Hitachi driver is used as the driver.
Opening the explorer, you can also make sure that the icon of the flash drive has changed, it began to appear as a hard drive, a regular disk. 
Now you can work with this flash drive as with a regular HDD: create partitions, specify an active partition, create dynamic disks, install software that does not work from flash drives, etc.
Important... On other Windows computers without this driver, the second device partition will not be available.
To uninstall the Hitachi Microdrive driver, open the disk properties and click the Update Driver button on the driver tab - the system will install the native driver by itself.
Advice... If after installing the Hitachi driver, the system stops booting with BSOD, you need to boot the computer from the Windows / Live CD and manually delete the following files:
- cfadisk.sys in the% windir% \ System32 \ drivers directory
- Directory "cfadisk.inf_amd64_ ..." from% windir% \ System32 \ DriverStore \ FileRepositoty
Reboot your computer
You need to understand that this solution will only work on the system on which the corresponding driver is installed.
I have long wanted to write this article, I think it will be very interesting to you. Received such a question from a friend, how to make a hard drive from a USB flash drive. So, we will analyze two options: changing the flash drive on 64-bit Windows and on 86-bit.
If you decide to use programs such as or others to view the USB flash drive, then you will not see it there, because there is a so-called descriptor Removable Media Bit (RMB) which is in any flash drive and forces Windows to identify such drives as removable, and not as a local drive. To fix this, we just need to delete this descriptor.
Why did I say there will be two options? Because on systems of different bit sizes, this operation will be carried out in different ways. This will be quite simple, so let's get started.
How to make a USB flash drive a hard drive on Windows x86?
To do this work, we need to download a special driver Hitachi Microdrive... You can download it from here.
Now let's find out the code of the device instance. In this case, we need to go to the device manager, there go to the tab disk devices... Look for your flash drive and right-click on it. In the window that opens, go to the tab "Intelligence", and in the drop-down list select "Path to device instance"... In field "Meaning" select the entire line and copy.
Let's move on to the driver. Unpack it to any place to begin with, and then, using any notepad, open the file. Find the item there and in the very last line, starting with the word USBSTOR we replace everything with what we copied in the device manager. Here's how it works:
At the end of the line, after REV_XXX, you need to remove a small tail:
After all that has been done, save the file.
Now, once again, go to the device manager and again open the properties of our flash drive. Let's go to the tab "Driver" and there we press the button "Refresh".
On Windows 7
Here we need to choose "Search for drivers on this computer" and select just the cfadisk.inf file that we changed with you.
On Windows XP
In this OS we choose "Install from a specified location", after "Don't search" and Install from disk... Select the cfadisk.inf file as the driver again.
After that, your flash drive should be recognized by the system as a hard drive.

How to make a USB flash drive a hard drive on Windows x64?
So, in this case we are downloading this archive.
Now go to the Device Manager, open the properties of our flash drive and go to the tab "Intelligence"... There, from the drop-down list, you need to select "Equipment ID"... In the "Value" field, you will need to copy all lines, except USBSTOR \ GenDisk and GenDisk.
The file F2Dx1.inf, which we downloaded, is opened with a regular notepad. In general, it is advisable to use Notepad ++. Having opened the file, we find the item in which we delete the first 5 lines, and then simply replace them with what we copied. The main thing is that each line begins with the phrase: % attach_drv% = f2d_install.
In addition, I want to say that the flash drive will be detected by the hard disk only on the system in which you performed this operation, since we just changed the driver in the Windows environment. If you insert a USB flash drive into another computer, then there it will be detected as a USB flash drive. That's all.
Unfortunately, there are often problems with the computer system that are not easy to solve. Someone needs to reinstall the OS sooner or later or restore the state of the PC. It is not always possible to access the hard disk drive in order to roll back the system or install a new one. Therefore, experts use a flash drive.
Using it is much more convenient than carrying a heavy hard drive with you. But to do this you have to learn how to do it. Many people think that it is difficult to do it. But if you apply the instructions, everything will be much easier. For everything to work out, you need to get a flash drive or memory card.
Preparation
Before you make a USB flash drive a hard drive, you need to prepare everything for this process. First, it's worth understanding multipartitioning. As practice shows, it will have to be abandoned, since flash media cannot cope with other partitions, but only work with the first block.
Next, you need to check if Windows works with the USB flash drive. After that, you will have to configure the definition of the drive as a non-removable device. A flash drive is almost always displayed as a removable drive, and the system should "think" that a hard drive is installed.
Before you make a USB flash drive a hard drive, you need to understand that if you do something wrong, you can ruin the device. If the configuration is incorrect, the drive will not be able to change its connection setting. Experts suggest using a special driver.
First step
Can a USB flash drive be made a hard drive? It is possible, and it will be easy to do, it is only important to adhere to the instructions. After connecting the flash drive, you will need to determine its type. This can be done in two ways: using two commands or a special menu.
To do this, open the Drive Control Manager. Using the combination Win + R, you can launch the Run menu. You will have to enter the diskmgmt.msc command in the search bar. Information about the drive appears.
You can also use In a new window, you will need to enter the following command - list volume. To identify a USB flash drive in the list, just look at the volume of the drive. You can also see the media type in the properties. Just go to the Volumes tab.
Second phase
How to make a USB flash drive a hard drive? After determining the type of drive, you will need to either change the connection or continue to work with it. If, nevertheless, the flash drive is defined as a removable device, you need to install the filter driver. To do this, you can use the Hitachi Microdrive utility. Thanks to it, you can not "physically" change the properties of the flash drive, but "deceive" the system by presenting the drive as a hard drive. Then you can make a USB flash drive a hard drive. The system will allow you to divide the archive into several blocks, which will have to work simultaneously. It will be enough to install the necessary software.
Stage Three
Next, you will need to find the media number. Go to "My Computer", find the connected USB flash drive and right-click. Selecting "Properties", go to "Details" and in "Properties" select "Path to device instance". The device number will appear below. In this line, you need to copy the characters after the second slash. The numbers are needed for the Hitachi Microdrive program. Next, you will need to find out the bit capacity of the system in order to figure out how to configure the drive.
To do this, just go to "My Computer", right-click on the free area and select "Properties". In a new dialog box, information about the system and its bit depth will be indicated. After that, it will be possible to customize the program.
Configuring Hitachi Microdrive Utility
If the computer works with 64-bit, you will have to go to the folder with the program. In it, find the cfadisk document, find the chapter cfadisk_device and cfadisk_device.NTamd64. After the slash, you will need to paste the copied equipment number. If the computer runs on 32 bits, the chapter cfadisk_device must be used. Find the line DISK & VEN_ & PROD_USB_DISK_2.0 & REV_P and insert the media number instead.
Fourth stage
The last step is to replace the drivers. If you have a 64-bit OS installed, you will need to configure one more parameter. For correct operation and installation of drivers, you will have to disable digital signature verification, otherwise the system will suspect deception. In addition, it can update itself, which, of course, is undesirable for the process.
The installation can now begin. Open the "Drivers" tab and select "Download Drivers". Here you need to specify the path to the folder with the utility driver. The system detects that the digital signature is disabled, and then asks to restart the PC. After rebooting, the flash drive will work as a non-removable drive.
Working with a hard drive
It is also possible to try to figure out how to make a bootable USB flash drive from a hard disk. Here it is enough to configure the hard drive to work with the OS. Through the "Control Panel" you need to go to "Administrative Tools" and "Computer Management". In the left column we find "Disk Management". All information about the hard drive partitions will appear in the table on the right. Now you need to format the hard drive and delete all partitions. After that, you will have to partition the disk and create a new volume. It will be enough to make it active and write the operating system there.
Alternative
Thinking about how to make a USB flash drive an external hard drive also leads the user to the Lexar Bootlt utility. It is not often talked about, although it is very simple and effective for this task.
The utility is free and helps to convert a USB flash drive into a fixed device. By the way, thanks to the same program, you can return the drive to a removable type. The software is designed for Lexar devices, but easily copes with other flash drives. Also works with Windows starting from XP version.
Still, there are some nuances associated with this program. The utility works with branded devices, but sometimes fails with other drives. It may crash with a USB 3.0 connection. And it is important to remember that after flashing any device, the warranty is lost.
After installing Lexar Bootlt, you need to run the program as administrator, select a USB flash drive from the list, and then click on the Flip Removable Bit command. Next, you need to save the change and restart the PC.
Working with a laptop
Can a laptop hard drive be made a USB flash drive? As practice shows, laptops are not eternal, so many users simply abandon the device or simply sell. But you can benefit from it by turning the hard drive into a drive. Usually it is enough to purchase a special box where the railway is placed.
This option is suitable for hard drives that were installed in older models. For example, you can use a 4GB to 100GB hard drive. Larger devices may not work over the rather slow USB interface. A box like this costs about $ 10-20. The kit comes with the necessary cable to connect the disk to a PC. To install the hard drive, there are screws that will securely fix the hard disk drive in the case.
Working with a hard drive and a flash drive is not easy. Care must be taken not to damage the drive. You should also follow the instructions for installing drivers and use the commands carefully.
Experts advise to immediately figure out how to remove the program drivers. In our case, we are talking about Hitachi Microdrive. To do this, open the properties of the hard drive and select update drivers. This process will automatically get rid of third-party installations and load the native driver.
Changing the parameters of the flash drive will lead to the fact that the user will be void of the warranty, so it is better not to experiment with a newly purchased device. In addition, if you make a mistake in the settings, you can lose your drive.
Modern users need to separate official and personal information. This can be facilitated by various reasons: virus attacks, confidential or proprietary information that should not be publicly available for obvious reasons. For this purpose, removable storage devices are used. Which one is better: USB stick or external hard drive?
Pros and cons of portable devices
In the question of what is better to choose for working with information, one should start from its importance, the speed of access to it and the requirements that are put forward to the carrier. A flash drive and an external hard drive have their own advantageous features and difficulties, they are worth paying attention to.
Benefits of an external hard drive
1. Convenient and durable.
2. Places in itself large files, there is no need to use multiple flash drives.
3. The ability to use the disk is unlimited, unlike a USB flash drive, which expires after a 10-thousandth recording.
The disadvantages of the device are as follows: the requirement for an additional power port is expensive, for a 250 GB device you need to pay up to three thousand rubles, low resistance to temperature changes.
There are two types of external hard drives: standard 3.5 "and miniature 2.5". The first one plays the role of increasing memory or computer. It is heavy and also requires additional food. The second one has less weight and size of memory, but at the same time has anti-shock properties.
Characteristics of the flash drive
1. Low price of the device. Let's say a device with 16 GB of memory will cost up to 800 rubles.
2. Convenient to use, takes up little space, practical in office work, and students.
3. Has a high speed of information reading or writing.
4. Low absorption of electricity, which is very important if the laptop is not connected to the network.
5. Large selection of shapes and colors of flash drives.
The disadvantages include the lack of a USB port in some gadgets, as well as the impossibility of playing information if the flash drive is "broken".
Answering the question which device is preferable: an external hard drive or a flash drive, I must say that it is better to have both on your desktop. Although the confrontation between the two necessary devices of the user will continue for a long time.
Information is measured in colossal volumes, there is a sorely lack of storage space. We need compact media that provide a large volume. It is clear that only an external hard drive meets these requirements.
Recently, a flash card has become the most popular type of information media, leaving far in history disks, floppy disks, cassettes and other technical tricks that have gone out of fashion and have lost their relevance. But how do you choose the right flash card from such a huge assortment of these little gadgets?
Instructions
Body material
Usually the drive is made of plastic or rubber. Choose metal if you are quite human, carry your drive with you at all times and do not want the contents to be damaged by some accidental sudden movement.
Choose a rubber case if you want the drive to last you longer - it does not slip, scratch or break.
The plastic case is more familiar and cheaper, so you can, if you are not going to perform some acrobatic tricks with the drive lying in an unbuttoned pocket.
Types of connector protection
The drive is either protected by a cap or is retractable. Choose a retractable if you tend to lose small items such as caps.
Storage volume
The volumes are very different. If you are going to only documents and a little music on a USB flash drive, then you don't need too large amounts of memory - 4 GB is more than enough. If you have big appetites, then choose from 8 GB. There are special flash drives for travelers, such a drive can be up to 64 GB. The price, of course, will be appropriate.
Drive design
You can find thousands of all kinds of flash drive design modifications and choose the one that pleases the eye and characterizes you the way you want it. Choose a design that suits your taste.

Anyone who regularly uses a computer needs a flash drive. Such a device is extremely convenient for transferring and storing a variety of information. Often, when choosing usb, people pay attention only to the volume of the drive. However, in fact, the device has a significantly larger number of parameters that need to be paid attention to.
Instructions
First of all, you need to decide on the volume of the drive. Even if now you need little space for information, in any case do not limit yourself to a drive with a minimum volume, because the price of devices of 128 MB, 256 MB, 512 MB is very low. The latter option is the most optimal in terms of price / quality ratio, but remember that it is impossible to store movies or other large files on such a drive. In this case, it is best to purchase a usb volume of 1-2 GB.
Then you can go to the baud rate. Today, most models write information at a speed of 10 mb / s, and read it out - one and a half times faster. There are faster, as well as slower drives, so when buying, you need to pay attention to the name of the specific device. For example, if the name contains the words "high speed" or "Ultra fast", then, for sure, such a drive is distinguished by its high operating speed. This parameter, like the reliability of the device itself, depends on the manufacturer. The most popular are from Kingston, SanDisk, Samsung.
Design and dimensions. In stores, you can find models in both medium and small sizes. In this case, it all depends on your preferences, because small devices are much easier to lose, and they are much more expensive. The device used to store information must be reliable in the first place, so you can find shock-resistant, waterproof models on the market. The USB plug does not have to be covered with a cap, in some models it can be hidden in the case.
Additional features. In stores, you can find copy-protected devices (this function is implemented using a special jumper). You can also find models with fingerprints, a crypto module that is used to encrypt data. Remember that extra protection will mean a higher price tag.

For those who want to buy flash drive you should know how to choose the right one. You should take a closer look at what functions it performs storage device whether it has limitations, whether it fits your computer. Use the special selection instructions.
Instructions
Select the software support you need: you can purchase flash drive with a special control chip. This control chip will help you to install flash drive with portable software, secure data, sync files and more. Software protections are very important to keep your confidential data out of sight of unauthorized persons. You can choose flash drives that are compatible with many operating systems and do not need any driver.
Check the baud rate. In fact, the transfer speed of USB 2.0 is about 14-24 Mbps. This is faster than USB 1.0, which is 1.5 Mbps.
Check the design and packaging. Look not only at the design and physical shape of the model, but also at the set of accessories that may be included in the kit: belts, cases, CD driver package, kit, manual lock, USB cable and others.
Check capacity. Choose a flash drive that at least suits your basic needs so that you don't have to buy another one in the future. Currently, the ideal size is considered to be 2-4 GB (this is enough for the day-to-day need to store the necessary data). And don't forget to find the model that suits your budget.
Check the warranty. Choose the warranty period that suits you. Average service life flash drive a is about 2 or 3 years old. People usually feel like they need more storage capacity after this period and they buy a new model.
Pay attention to the manufacturer of the device. Please select flash drive with high reliability and responsive service center. Do not forget to make sure of the credibility of the manufacturer and distributor. Make sure you can easily contact them for support. This will be helpful if you start to experience problems with your drive or want a warranty exchange.

A flash card or flash drive is a portable storage device of electronic information, which is small in size and low in cost. This is a handy device for all computer users. When choosing a flash drive, people are often guided only by the amount of memory and the price, without knowing about other important characteristics. To buy a good flash drive, there are several criteria to choose from.
Instructions
Volume is the main quality of a flash drive. Consider how much memory you need for normal operation. If you need to transfer text information from one computer to another, and the tasks of the flash drive will be limited to this, choose the minimum amount. And for recording and storage, photos, music or office software, calculate yourself a sufficient amount of memory: at least 2 gigabytes, for high quality movies - 16. It is better to buy a drive with a margin, for emergencies.
The next important characteristic is the reading speed. Today, all flash drives are connected to a computer via USB ports, and recording is done at a speed of up to ten megabits per second, and reading is even faster. If the device has “speed-hi” or “ultra fast”, it means that it has a higher speed.
Pay attention to the manufacturer. Well-known developers produce quality flash cards - for example, Kingston, Transcend or Samsung. But there are times when unknown companies sell these flash drives in their packaging, so there is an opportunity to buy a good device at a lower price.
Find out about the additional features of the flash drive. For example, some models have copy protection, which is done with a password or fingerprint reader. There are also devices that support the U3 function, which allows you to work at the computer without leaving any traces.
The appearance of a flash drive also matters for many. It all depends on your taste - manufacturers provide a huge selection of different designs, shapes, sizes, materials. There are devices in the form of key rings, business cards, pendants. Size is important for more than just an aesthetic point of view, as larger models will not fit the adjacent USB ports.

- How to choose a flash drive
Any user constantly working with a computer needs a USB drive. A flash drive is extremely convenient for storing a wide variety of information. However, when buying, most pay attention only to the volume of the device. In fact, a USB drive has a much more significant number of parameters to consider when choosing.
Instructions
First, you need to select the volume of the usb drive. Even if at the moment you need quite a bit of information space, try not to buy devices with a minimum volume, because the price of 512 MB and 1 GB usb drives is very low. The second option is the most optimal for storing text and graphic information, but remember that it is impossible to store high-quality films and other large files on such a flash drive. In this case, it is best to buy a 2-8 GB usb drive.
Then pay attention to the baud rate. Most modern USB drives write data at a speed of 10 Mb / s, and transfer data 1.5 times faster. Both faster and slower models can be found in specialized stores, so check the name of the device when buying a USB drive. For example, if the characteristics of a flash drive contain the inscriptions "Ultra fast", "Very High speed", then most likely the device has a high data transfer rate. This parameter, like the quality of the usb drive itself, depends on the manufacturer. The most reliable are flash drives from SanDisk, Kingston, Samsung.
In stores there are models of both medium and very small sizes. When choosing a design, it all depends on your preferences. However, remember that small sticks are much easier to lose, and their price is much higher. A device designed to transfer and store information must be reliable, so when choosing a USB drive, pay attention to shock-resistant and waterproof models. The USB plug must be protected from external influences, on some models it has a cap, on others it is hidden in the case.
In addition, there are models equipped with special copy protection. You can also find devices equipped with a fingerprint scanner or cryptomodule (designed to encrypt information). Additional protection also affects the price of the device.
Today, no mobile device, be it a phone, laptop or camera, is complete without flash memory. It allows you to significantly expand the amount of recorded information and save it for many years.
Instructions
When choosing a flash card, be sure to consider the type and model of the mobile device for which it will be intended. Usually, the description for the device indicates the type of suitable memory card.
The amount of flash memory is also of great importance. But here you should already pay attention to individual needs. If a small amount of information will be stored on the card, for example, pictures or melodies, a small amount will do. Photos from a professional camera or movies will take up much more space. On average, a 256 Mb card will fit about 30 minutes of video or 100 high-quality photos.
To avoid problems with the compatibility of flash memory and mobile device, it is better to opt for more famous and widespread cards. Today there are seven of them: CompactFlash (CF), IBM Microdrive, SmartMedia, Multimedia Card (MMC), SecureDigital (SD), MicroSD and MemoryStick. Each of them has its own pros and cons, and their choice depends on personal preferences and needs. But according to analysts, the most common and versatile memory cards of them are CompactFlash and SD / MMC.
Choosing a flash memory, do not disregard the speed of its reading, writing and the degree of protection of the stored information from accidental damage or erasure. Naturally, the higher these indicators are, the better.
Pay attention to such an important selection criterion as the price of the goods. High cost is not always an indicator of better quality. Sometimes it will simply depend on the tiny size of the flash memory. Better still rely on the versatility of the card.
If there is such an opportunity, when buying a flash card, purchase a special adapter that will allow it to be used in other mobile devices.

A flash card is a portable storage device for electronic information. Its advantage is its compact size and affordable price. When choosing a flash drive, you should pay attention not only to the price and amount of memory, but also to other equally important characteristics.
1. Volume. You should consider in advance how much memory is required to work with information. If the function of the flash drive will be limited to the transfer of text data from one personal computer to another, you should select the minimum amount of memory. For recording and storing video and music files, office programs and photos, the memory capacity ranges from 4 to 32 gigabytes. It will be prudent to purchase a storage medium with a margin.
2. Speed of reading information. All standard flash cards are connected to a computer via a USB port. And the recording of information reaches 10 MB per second. If you want to purchase a device with a higher speed, you should pay attention to the following inscriptions: "ultra fast" or "speed-hi".
3. Brand. Well-known manufacturers of flash drives that guarantee the quality of goods: Transcend, Kingston and Samsung. Flash cards of these companies are sold in their packaging by other little-known companies. In this case, it is possible to purchase a quality device at a lower price.
4. Additional features. For example, copy protection (allows you to access data solely by setting your password or reading the owner's fingerprints). Support for the U3 function (allows you to work in a hidden mode, excluding the presence of traces of stay).
5. Appearance. At the moment, there is a huge selection of designs, dimensions, materials and shapes. A huge selection of drives in the form of jewelry, stationery, key rings, business cards and credit cards allows you to choose a flash drive to your liking. When choosing a drive, keep in mind that bulky models may not be suitable for nearby USB ports.
USB sticks are one of the most popular ways to transfer and store data. Flash drives are almost irreplaceable data storage that must be chosen wisely and carefully.
Today it is almost impossible to imagine life without a USB stick. They are used everywhere: at work, in the car, at home, at school, etc. Of course, the buyer, when he comes to an electronics store, can choose absolutely any flash drive, but one should not hope that it will be able to work long enough. In order to find a really good, high quality and reliable USB drive, you need to have some knowledge. In the store, sales consultants can advise you on a product that is not of the best quality, even if the flash drive has a large volume. In order for your final choice to fall on a good product, you must first of all decide on the parameters, namely: the maximum memory capacity of the USB-drive, the speed of reading and writing files, the size and strength of the case.
Memory
The amount of memory, for the vast majority of buyers of USB-drives, is the fundamental factor on which they focus absolutely all their attention. On the one hand, this is correct, but on the other, it is not. Today in the store you can find flash drives with different amounts of memory (from several megabytes to 32 gigabytes and more). This factor, of course, affects the cost of a flash drive, but all the same, USB drives are relatively cheap, especially since this market is constantly evolving. Better to opt for a good USB drive, which will have at least 16 or 32 GB of memory.
Data read and write speed
The speed of reading and writing files is far from the last value, although many do not even focus on this. This approach is extremely outrageous, since you can buy a USB flash drive with a large amount of memory, but uploading data to it and viewing it can be quite problematic. Moreover, with a poor write speed, the user will not be able to completely fill the USB flash drive or at least fill its space minimally. It is best to choose a flash drive that has a write and read speed of at least 16 MB / s.
Case size and strength
As for the last aspect - the size and strength of the case, it is best to give your preference to those options that have fewer complex elements. In the event that, for example, a flash drive slides out of the case, then most likely it will not be able to serve you faithfully for a long enough time. It is best to buy a regular USB stick with a lid. As for the size itself, you should not buy an irregularly shaped flash drive or just oversized USB drives. This is due to the fact that most often you have to carry a USB drive with you in your pocket, for example, in a jacket, and you will hardly be able to put a large drive in a small pocket.
Particular attention should be paid to the most important parameter of flash drives - the speed of reading and writing information. This is the most important parameter that must be taken into account. Many users do not even think about this characteristic, and very much in vain. If the user buys a cheap flash drive, he risks losing a lot of time reading and writing information. The fact that this parameter is important, you will see when you download a movie to it or for about two hours.
The body of this device is also important. It must be simple and strong. The fewer moving parts on the flash drive, the better. If a flash drive pops out, then it most likely can break in just a couple of months.
The body must be flat. If the body is either convex, or with some or curly images, then you most likely will not insert anything into the adjacent USB connector. For example, if you need to transfer files from one flash drive to another flash drive.
There is one very interesting parameter - recognition of the owner using fingerprints. It's everyone's business, but if you take a flash drive with such a degree of protection, then it's better to think about it: many complain about that recognition and errors. In general, there is no value from such a "gadget", but it costs a lot of money.
And, of course, you should take a flash drive with a USB 3.0 connector, as this will allow you to use high read and write speeds. The most popular manufacturers are rightfully considered: Silicon, Kingston and Transcend.

When choosing a means for storing and transferring information, many users may face difficulties in choosing, since today on the shelves you can find CDs, flash drives and external hard drives intended for this.
Flash drive vs. compact disc
Today there are a huge number of different ways and means for storing and transferring information, for example, from one computer to another. When choosing such a device, many users may face selection difficulties. For example, what is better to buy a USB flash drive or disk for these purposes? It should be noted that in this case, the choice can be made towards the flash drive. The point is that, firstly, the USB drive is smaller in size, and, secondly, the amount of its memory is in no way inferior to modern CDs and DVDs. In addition, the cost of such flash drives today practically does not bite, which means that everyone can easily buy even a 16 gigabyte USB flash drive.
USB flash drive or external hard drive?
Naturally, it is much more difficult to choose between a USB stick and an external hard drive. Of course, even a 64 GB flash drive will cost much less than an external 500 GB hard drive, but this is directly related not only to the maximum device size, but also to the data transfer speed and quality.
What is better to choose in the end? It is believed that in this case, USB sticks benefit exclusively from their mobility. They are much smaller, it is more convenient to carry them to work, etc. As a result, it turns out that if you need such a drive not only at home, but, for example, also at work, then, of course, it is worth stopping on a USB flash drive. In the event that the drive will be used quite rarely and only at home, then it is better to stay on an external hard drive. First, everyone can buy it today at an affordable cost. Secondly, its volume usually ranges from 500 GB to several terabytes, and this will allow you to store much more information than on a regular flash drive. Thirdly, the speed of processing and saving data on an external drive is much higher than that of a conventional flash drive. A significant difference and, possibly, the disadvantage of such disks is their size. The owner of the device, of course, can carry it with him to work, but for this he will have to pack it, take with him a cord to connect to a personal computer, etc. The flash drive, on the other hand, can be simply put in your pocket.
As a result, of course, everyone chooses what is better to choose - a USB flash drive or an external hard drive. If you carefully study all the characteristics and options for the operation of these devices, you can always opt for a form that is more suitable for work or study, which will help you save and transfer the necessary information every day.
To increase the disk space of the Eee PC without any soldering will help not a tricky solution, namely, to use the SD slot as an additional disk of the system. In this case, the system will recognize it as a hard drive and allow you to install additional programs on it. I recommend using SD HC card - 8GB 6 series, manufacturer according to your taste. As a result, we get +8 GB of "disk space".
Purpose: to make you see the flash drive of the Partition Magic program, Acronis Disk Director, etc. to create partitions on the flash drive, including hidden, formatting and other operations.
Loading the Hitachi Microdrive mini-hard drive driver. We unpack it into a temporary directory. Open the file with a text editor cfadisk.inf
Find the section:
USBSTOR \ DISK & VEN_ & PROD_USB_DISK_2.0 & REV_P
Connect the flash drive, go to the device manager. Right click on My Computer -> Manage -> Device Manager -> Disk Devices... Find the flash drive in the list, open its properties, go to the Details tab. Select and copy to the clipboard (Ctrl + C) "Device instance code" (in windows se7en - "Children"). In our case, this is the line
USBSTOR \ DISK & VEN_USB_2.0 & PROD_FLASH_DISK & REV_1.00 \ 7 & 138BF0DA & 0
Moving on to editing the file cfadisk.inf... Replace the highlighted line below
% Microdrive_devdesc% = cfadisk_install, USBSTOR \ Disk & Ven_LEXAR & Prod_JD_LIGHTNING_II & Rev_1100
% Microdrive_devdesc% = cfadisk_install, USBSTOR \ Disk & Ven_JetFlash & Prod_TS1GJF110 & Rev_0.00
% Microdrive_devdesc% = cfadisk_install, USBSTOR \ DISK & VEN_ & PROD_USB_DISK_2.0 & REV_P
to the "device instance code" (xp) or "children" (se7en) of our flash drive, as a result we get:
% Microdrive_devdesc% = cfadisk_install, USBSTOR \ Disk & Ven_LEXAR & Prod_JD_LIGHTNING_II & Rev_1100
% Microdrive_devdesc% = cfadisk_install, USBSTOR \ Disk & Ven_JetFlash & Prod_TS1GJF110 & Rev_0.00
% Microdrive_devdesc% = cfadisk_install, USBSTOR \ DISK & VEN_USB_2.0 & PROD_FLASH_DISK & REV_1.00
Device Instance Code Line \ 7 & 138BF0DA & 0 do not write down. Save the file cfadisk.inf.
We replace the standard driver with Hitachi Microdrive.
In XP: In the device manager, in the flash properties, go to the tab Driver → Update → Install from Specified Location → Don't Search → Have Disk
In Se7en: In the device manager, in the flash properties, go to the tab Driver → Update → Search for drivers on this computer → Select a driver from the list of already installed → Have disk
select the file cfadisk.inf, ignore the message about an unsigned driver.
We make a safe removal of the flash and connect it again. (Note: For SD, the procedure is optional)
So that is all!! Your flash drive is ready for use. Good luck!!!
