Hard Drive from Flash

When there is not enough free space on the hard disk, and it does not work, it is necessary to consider various options to increase the space for storing new files and data. One of the simplest and most accessible methods is to use a flash drive as a hard disk. Medium-sized flash drives are available for many, so they can be freely used as an additional drive that can be connected to a computer or laptop via USB.


A regular USB flash drive is perceived by the system as an external portable device. But it can easily be turned into a drive so that Windows will see another connected hard disk.
In the future, you can install an operating system on it (not necessarily Windows, you can choose among the “lighter” options, for example, based on Linux) and perform all the same actions that you do with a regular disk.

So, let's move on to the process of converting USB Flash to an external HDD.

In some cases, after performing all of the following actions (for both Windows bits), it may be necessary to reconnect the flash drive. First, safely remove the USB drive, and then reconnect it so that the OS recognizes it as a HDD. For Windows x64 (64-bit) Download and unzip the F2Dx1.rar archive. Connect the USB flash drive and launch the "Device Manager". To do this, just start typing the name of the utility in the "Start".

Starting Device Manager Method 1

Or right-click on “Start” and select “Device Manager”.

Running Device Manager Method 2 In the "Disk devices" branch, select the connected flash-drive, double-click on it with the left mouse button - the "Properties" will be launched.

Properties of the flash drive in the Device Manager Switch to the Details tab and copy the value of the Equipment ID property. You do not need to copy everything, but before the USBSTOR \ GenDisk line. You can select lines by holding Ctrl on the keyboard and left-clicking on the desired lines.

The example in the screenshot below.

Copying the hardware ID in the Device Manager The F2Dx1.inf file from the downloaded archive must be opened with Notepad. To do this, click on it with the right mouse button, select "Open with ...".

Open file with

Select Notepad.

Selecting a program to open the file Go to the section:


You need to remove the first 4 lines from it (that is, lines up to% attach_drv% = f2d_install, USBSTOR \ GenDisk).

Deleting lines from the f2dx1 file Paste the value that was copied from the Device Manager, instead of the deleted text. Before each inserted row add:

% attach_drv% = f2d_install,

It should turn out, as in the screenshot.

Lines from the Device Manager in the f2dx1 file Save the modified text document. Switch to the "Device Manager", right-click on the flash drive, select "Update drivers ...".

Update the flash drive driver in the Device Manager Use the "Search for drivers on this computer."

Selecting the update method Drivers in Device Manager Click on “Browse” and specify the location of the edited file F2Dx1.inf.

Select file f2dx1 Confirm your intentions by clicking on the "Continue installation" button. After the installation is complete, open the Explorer, where the flash will appear as “Local disk (X :)” (instead of X there will be a letter assigned by the system). For Windows x86 (32-bit) Download and unzip the Hitachi_Microdrive.rar archive. Follow steps 2-3 from the instructions above. Select the "Details" tab and set the "Path to the device instance" in the "Property" field. In the "Value" field, copy the displayed string.

Copying the path of the instance of the device in the Manager devices The cfadisk.inf file from the downloaded archive needs to be opened in Notepad. How to do this is written in step 5 of the instructions above. Find a section:


Reach the line:

% Microdrive_devdesc% = cfadisk_install, USBSTORDISK & VEN_ & PROD_USB_DISK_2.0 & REV_P

String to edit

Remove everything that comes after install, (the last should be a comma, without a space). Paste what you copied from the Device Manager. Remove the end of the inserted value, or rather everything that comes after REV_XXXX.

Deleting part of the device instance path You can also change the name of the flash drive by going to


And by editing the value in quotes in the string


Editing the name of a flash drive Save the edited file and follow steps 10-14 from the instructions above.

After that you can break flash into sections, install an operating system on it and boot from it, as well as do other actions, like with a regular hard drive.

Please note that this will only work with the system on which you performed all the above actions. This is due to the fact that the driver responsible for recognizing the connected drive has been replaced.

If you want to run the flash drive as HDD and on other PCs, then you need to have the edited file-driver with you, and then install it through the “Device Manager” in the same way that was mentioned in the article. We are glad that we could help you in solving the problem.
