I purchased RestoreIt for my XP computer. It was a great program but it would not run on Vista so I purchased Drive Clone Pro 3.5. When the time came to use the disks created for a complete backup the disks could not be read. I contacted Farstone and was told that version was unstable. They would give me 30% discount which I think is unfair given that the orginal software which I bought in good faith had a known problem and created errors in the disks so the image could not be restored.
