Lorien--I used the software that came with the Western Digital USB external hardware. I don't believe it's an image backup--it backs up using basically same folder/file as computer. Step by step I used: Clicked advance restore (backup from another computer); drop down box shows available locations for a backup and I choose my Drive H (the western digital drive); the computer recognizes the drive--no problem; I am given a choice of which backup (date & time) I want to use (I backed up once a week since 2008 so have MANY backup files) and I select the first one (the origional full backup that all the subsequent backups reference)--note that while I am given the choice of which backup to use, I get "backup location not available" comment next to every backup file; Again, I select a file, hit restore and it muddles along for awhile and I get "Restore Complete"--but no files show up (for example, no excel files, word files, pictures, itunes music etc even thought they were in the respective backup file)
