can't remove write protection on sandisk usb drive.

have tried diskpart to clear readonly attributes but still unable to format sandisk usb drive
Since diskpart do not work properly then try regedit method.


Input regedit in Windows search box, and then press enter.
(Note: May require to select "Run as administrator")

Locate the following path in Registry Editor:


(If the StorageDevicePolicies doesn’t exist, create it manually.)

Then double click WriteProtect and set the value from 1 to 0, then press OK.

Restart your computer, and re-plug the SanDisk USB flash drive or other storage devices into your computer, check whether the issue is solved or not.
