A friend dropped my USB drive and now none of my computers see it at all (two Windows XP's and one Windows 2000). I've dropped flash drives before, and figured that I may have knocked something off the circuit board. So, I took it apart and everything appears to be fine. Now, after it was dropped, it stopped working--so, that is probably what created the problem. But, what I'm trying to find out is this: if nothing was broken on the circuit board, why would it stop working? If anybody has any advice they could offer me (and/or any recommendations for reasonably priced USB data recovery software), I would much appreciate it.
