USB device write protected

Hi,

After reinstalling my OS “without any reason” every usb sticks and even one external hard drive become Write Protected. Strange thing I didn’t have any problem to format them but still when I tried to download something on them, I receive message: “The disk is write protected, remove the write-protection or use another disk”. I clean attributes in Diakpart. I used “hard disk low level format application” to format and everything was going smoothly but they are still not useful. I tried also regedit to check what number was in StorageDevicePolicy but I didn’t have there QWORD64 with name “Write Protect” which I created with value date “0”.
Now, I don’t have any more ideas what I can do else to fix this strange problem. I’ll really appreciate if someone help me to solve it.
Thanks in advance.

When drives become write protected it often indicates a drive problem.

When multiple drives are affected, it may be related to unexpected shutdowns and restarts (weather, power outages, etc.)


Check the drives using another Windows computer.

If they still display write protected then please test the drives to see if they pass or fail various drive tests using:


Sea tools long generic test (using Windows or bootable versions)



HD Tune Full Error Scan: (free or trial) HD Tune website

or

Macrorit Full Error Scan: Check Hard Disk for Bad Sectors | Scan Disk on Windows


Test USB drives using: GRC | ValiDrive


If the drives pass the above tests there are additional tests.
