I used Spinrite to repair a drive on an 8100c once so knew about that but have not replaced a drive. This article talks about the Spinrite option (www.grc.com — he has some great stuff) and suggests you can replace the drive/restore images The author also talks about the 9100c. Perhaps you can get specifics there.
Thanks, I appreciate that. I don’t have a problem with the image though, it is a physical problem with the drive.
