My flash drive was working fine until today. I plugged it in and tried to save something to it and it said "this disk is write-protected." I went through the registry editor and tried to remove it but I had the same problem. I also tried two of my friends' flash drives and I am getting the same error message, so I know that the problem is with my computer and not the flash drives. Can somebody please shed some light on what could be wrong and how to fix it? Thanks in advance!

Hi,

You may have  to modify the registry key StorageDevicePolicies:

Note: before doing the steps below, please backup your registry first.

1. Click Start, type regedit.exe and hit ENTER.
2. Go to the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrrentControlSet\Control\StorageDevicePolicies.
3. Search for a key WriteProtect.
4. If there is such a key change the value to 0.
5. Repeat the same for ALL HKEY_LOCAL_MACHINE\SYSTEM\ControlSet00*\Control\StorageDevicePolicies (replace * with number).

If you cannot find the key StorageDevicePolicies , create it manually:

1. Right-click HKEY_LOCAL_MACHINE\SYSTEM\CurrrentControlSet\Control\ and select New -> Key.
2. Enter the name StorageDevicePolicies.
3. Click on the new registry key StorageDevicePolicies and on the right pan right-click, select New > DWORD and give it the name WriteProtect.
4. Double click on it and set its value to 0.
