Write protected USB Flash drive

[Skurge]

So I gave my USB flash drive to a friend, unsurprisingly he returned it with a virus. Now I can't format the drive as it keeps saying its write protected.

Someone said I should use Active killdisk. Well it was taking 3hrs to format the drive so I canceled. Now the drive doesn't have a drive letter and I can't assign it one in disk manager.

Using Win7 64bit.

What do I do now?

You should be able to fix it using disk management.

Click start, type diskpart in the search bar & hit enter.

Try these commands:

list disk (make note of your drive number)
select disk (your drive number)
clean all

Then drive management should work for you.

Still tells me "the media is write protected"

Did clean return successfully? Try clean all, I updated my instructions with that as it may be more effective.

I'm Still getting the same error.

What are you trying to do when you get the error? Is the clean not working?

Whenever I type in the clean command it just gives me that error.

Try using vconsole's USB flash drive tester. It does raw writes to the flash drive, bypassing the filesystem. If you do the full test, it will wipe out everything on the flash drive. See if that works. vconsole.com
