I recently used ATI 10 to clone my old 40Gb drive to a new 250Gb drive. This went well and the new drive boots without problems to Win XP. The old drive had appeared to be going bad (some blue screen errors) and chkdsk r fixed some problems. However the Hitachi 'Drive Fitness Test' didn't show any problems. I decided I would use the old drive as a target to test restore from backup. I created a full image backup to a network drive and verified it. Then I booted the ATI product CD, checked I could see the backup on the network drive and did a couple of file restores - all OK. Next I temporarily removed the new drive and reinstalled the old one intending to test a full restore of the drive (less than 40 GB of data to restore). I then attempted to boot from the ATI CD but this time it would not boot. After the ATI splash screen it hung on 'Acronis Loading....'. Tried a few times all with same result, so no success so far with my restore test. After switching back to the new hard drive, I could once again boot from the ATI CD. If the old drive is invalid in some way would that prevent ATI from booting? I will try getting the latest build, but I'd lbe grateful for any insights anyone can offer as to what is happening here.
