External hard drive will not load. Error message about I/O error. Tried on both a XP and vista system. I got a couple different data recovery programs and they could read it either. I REALLY REALLY need the info off this drive. can i get a boot disk or anything to get the info off? at one point the vista system siad i needed to format the drive. i dont want to do that becasue i'll lose my files...right?
