I have a pen drive ( Transcend) and I can do nothing with it. When I try to access it says "drive is not formated". Format it said the disk is write protected. I try using windows setup to re-patrition. Not work. Hiren's boot cd with Format tool was not responding when I apply operation to the disk. Format tools didn't work. But XP and SEVEN did say that the pen is healthy? Thank anyone that would give me the idea.
