My flash disk Write protected

4 gb flash disk

My initial thought would be that it's not so much write protected as simply worn out. Flash cells have a finite number of times they can be written to, and given the average age of a 4GB drive, it's probably just at that point. So you just get a new one, copy everything over, and toss the old one.
