Have a Maxtor One Touch III 500gb external hard drive. Initially set it up, formatted literally backing up my life to it and nine months down the road all of a sudden my computer does not acknowledge the drive. I have rebooted with the drive off. I have uninstalled / reinstalled software and drivers, changed out the cables. Even more interesting, I have a "removable disk" showing up on My Computer with the letter "F" and when I try to launch it, it tells me there is no disk in the drive. Disk manager does not acknowledge the drive either, at least not that I can tell. PLEASE HELP!
