Hi,

Have you tried to perform a CLEAN or CLEAN ALL command from DISKPART in order to wipe the drive?

Disk - Clean and Clean All with Diskpart Command

Then attempt the format after that.

Golden

Check whether this helps.

1. Shutdown your computer
2.Plug-in your USB drive
3. Switch on the computer and get into safe mode by pressing F8 key.
4. In the Advanced Boot Options, select Safe Mode with Command Prompt
5. If your USB drive letter is D then C:\windows\system32>D: [ENTER]
6. D:\>format D: [ENTER]
7. If asked (Y/N), press (Y) [ENTER]

Now a full format will be done hopefully removing write protection from the USB drive.

Thanks Golden. I tried the method and it is still not working. I am not able to format it and even run CLEAN or CLEAN ALL command.

Thanks jumanji....as I have mentioned that the advanced boot option did not help at all. I still get "Disk is write protected".

1. What is your pendrive make/model?

2. Does it have a switch?

3. How old is your pendrive and was it functioning OK before?

4. Do other pendrives work?

4. Do other pendrives work?
YES


anyways, I am thinking on quitting this as this is only a 4GB drive. But, the question remains why the write protection is not getting removed?

When too many bad sectors are created in a flash drive and the reserved sectors mapping those out and replacing gets exhausted, the flash controller in the drive will not allow one to write anymore and makes it write protected. Your pendrive has reached its end of life.

If within warranty, you may get a replacement.
