Some operating system has already have this StorageDevicePolicies in their system.

Write Protection on any portable USB Device can be applied by the physical lock provided on the card adjuster or some times provided on the pen drives, so make sure to make your drive not write protected by moving the lock in right direction.

But even after moving the physical lock for write protection the problem can happen due to some virus action.

Answer 3

You can usually find a write-lock switch located on the drive itself. If there is no such switch, you can check under "Properties" when the drive is open; if you do not have write access, you may be able to grant it under the security tab. Finally, some drives mount as if they were a CD-ROM drive. These are usually non-writable permanently, having a software protection in the controller. They can only be unlocked by the manufacturer, and you have to have a great reason for doing so (so far, only Cruzer U3 drives have this feature).

Answer 4

your best bet would be to consult the manufactures website for that info.

Answer 5

To remove the write-protection from your Flash Drive there should be a switch at the back of it. Flick the switch and your problem should be solved.
