How to Format a Write Protected Disk

I have "Jetflash Transend 8GB" flash drive. I can't format it. When i try to delete or format it this error appears "The disk is write protected" so how do i format it. That flash drive contains some Trojan horses.

hi there see if this helps you

Boot your computer into safe mode. To do this, restart your computer. While it is rebooting, continually press the F8 key until a menu pops up. From that menu, select "Safe Mode."

Open Windows Explorer. To do this, wait for your computer to finish starting in Safe Mode. From the desktop, press the windows key and "E" simultaneously.

Right-click on the disk you're attempting to format. Select the "Format" option from the pop-up menu.

If the steps above do not work, try editing the registry directly. Select START (bottom left of your screen) and RUN to open the run dialog box. Type "regedit" (without quotes) into the dialog box that appears, and press enter.

Navigate to the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies. Change the value for the key "WriteProtect" to 0


For formatting a USB drive that is write-protected, there is a software tool that can help. If you can't format your write-protected drive with the steps outlined above, try downloading and running the free HP USB Disk Storage Format Tool >>> HP USB Disk Storage Format Tool - v2.1.8 Download - EXTREME Overclocking

Unless the pen is physically write protected, the error message could be due to a defective drive or the root of the drive being full. In the latter case, try creating a new folder at the root of the drive and dump all the files into it.

Otherwise, reformatting is the only way out. If all the registry tricks dont work, theres a brute force tool available from apacer that many people have found effective.

Other things to try would be formatting with a 3rd party tool like the HP format utility or from outside windows.

WITH A WRITE PROTECT VALUE OF 1
