Hi, I used True Image Corp. Workstation v 8.0 (build 1,158 ) to create a full backup of a Dell desktop PC. The resulting file is 11.7 gigs, and was created without error on an external USB hard drive. I carried the hard drive to another PC with the same version of TI, and tried to mount the image (to make sure it worked). I get the following error: "Cannot assign a drive letter to a partition from the image archieve." The Explore Image Wizard can read the file, and shows my comments and the partition structure. I am concerned that this backup is no good. I did run a Check Image on it, and it finished with the simple "Operation has succceeded." So, what can I try next? I know I should go back to that PC and try to mount it, but that is not very convenient at the moment. BTW the image was created in Windows, so the person could continue to work during the backup creation. Thank you for your suggestions.
