We have a 3 month old 750gb Maxtor external storage device that is not being accessed by our PC running on Windows Vista. The device shows in my computer, shows 630gb of info, yet files all show 0 bytes. When try to open a file, I/O error is shown. We have tried running unit on two other PC’s, one running on Vista also, 2nd on XP. Nothing is able to open either. We also tried opening on both a firewire and alternate usb cable. Tried a diskcheck in DOS, and that did not show anything. Our choice seems to be to send out for data recovery. It seems like there should be a way to restore communication between the storage unit and the PC. Has anyone been able to reach an positive result in this type challenge? Seems as we look around it has happened to others. Would really like to hear from anyone successful…
