How to remove write protection from sandisk pen drive



Go from Start to Run and into the Open box, type regedit then press Enter.

From the File menu, select Export then note the name and location of the backup you're about to make in case anything goes wrong. This is extremely important before altering your Registry.

That done, then navigate through the hives to this key:-
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control

Double click on StorageDevicePolicies and then on Write Protect then change the Value data from 0 (zero) to 1 (one). The File menu then Exit gets you out.

If the StorageDevicePolicies key doesn't exist, you will need to create it, then create Write Protect and proceed as above. Post back if you need to know how to do that.

 

I believe the Sandisk comes formatted Fat32, meaning you can only add 4GB, unless you formatted it to NTFS. And the first time the device is removed from the system, that files structure is locked in. Registry edit and other fixes will not work, IMO
