Sorry to hear the bad news frnkbrwn.
Since you have nothing to loose at this point, try doing a Quick format of the drive, not a Full format, then try the file recovery tools. Either the ones from work or from this posting: http://forums.sandisk.com/t5/All-SanDisk-USB-Flash-Drives/How-to-recover-the-data-from-Cruzer-Micro-4GB-Accidental-Erase/m-p/294499#M4996
Good luck.
