Was the drive that has the data on it you need, the destination or the source drive in the imaging operation? If it's was the destination drive, Ghost will have very likely wiped the fat table and depending on your settings, adjusted your partition table to suit the image you were working with. So whatever tools you use, they must be able to read the disk even if the partition tables are messed up. You should not make any changes or writes to the damaged drive whatsoever, the drive should be treated as "read only". So make sure any tools that you use do not alter the drive in any way. Likewise, only ever save recovered data to a different drive. I personally would perform a bit copy of the damaged drive to an image file and work with a copy of that mounted on another machine, rather than work on the damaged drive. If you mess up, it's just a matter of copying the file again and having another go, there's no risk to the data on the target drive. If on the other hand the drive you need to recover from was the source drive in the imaging operation, then Ghost sometimes installs its own boot files and reboots to run its imaging script. If the operation is interrupted for some reason, those boot files are not removed because Ghost didn't complete its script. If that is the case, you can usually restore the original boot files using the inbuilt tools and utilities for your version of the operating system.
