Hi - I've just purchased this in order to keep backups of a home machine. The machine it's on is an IBM ThinkPad T42 in a docking station. I've backed up the C drive with the OS to an external drive, then restored to another drive in a tray in the docking station. I then pulled the regular drive and replaced it with the restored drive. When I boot I get the message, A disk read error occurred. press CAD to restart. I tried the MBR fix off CD and that didn't help. Anyone have any ideas? I'm going to try to put the drive in first, then boot from the CD and restore to the drive while it's in, setting the drive letter to C. The whole idea here though is to just pull the drive and place it in the Thinkpad to get going again in case of a failure, that the dream.
