Hi,

 

As my USB key is protected, I can't format anymore.

 

I tried with Hiren Boot CD, deleting the partition with different programs listed on this CD but it can't remove it. The same results I got doing a format.

 

Here is the specification of my USB key:

Brand: Hynix

Capacity: 16 Gb

VID = 090C  PID = 1000

 

Any software to remove definitely this protection will be helpfull.

 

Thank you!

Usually when a flash drive becomes write protected it can no longer be saved unless there is firmware for the drive. A flash drive can become write protected because of a firmware fault or if the drive is fake. Cheap fake drives are advertised as having a larger than actual size. Once the actual size is reached the drive becomes write protected. 

 

If firmware is not available for your drive I am afraid it cannot be repaired.

I also tried with RMPrepUSB and I couldn't format as it write protected.

Not that I know of. The drive is write protected and cannot be formatted.

 

I doubt it will work but have you tried using the diskpart command to wipe the drive then format? Attach the flash drive.

 

At a command prompt type

 

diskpart

list disk

select disk X     Where X is your flash drive. It is very important you select the correct number associated with the flash drive as it will be wiped

attributes disk clear readonly       Will clear the read only attribute if at all possible

clean all            This will zero wipe the drive

exit

exit

@JohnC_21

 

I already tried with diskpart, but unfortunately, I got a message that it was protected

Your flash drive has failed and unfortunately you will need to purchase a new one.

Ok, thank you anyway.

 

All in all, how can I add files at a moment and then suddenly, it became impossible to do it ? 

Do you think, this was fake or it was due to those bad clusters ?

It could be a fake or if the firmware of the USB flash drive determines there is a fault then the drive becomes write protected. Usually fakes are high capacity drives that are very inexpensive.

 

There are tools available to determine if a drive is fake.
