Hi Ben,
Windows 7 Image BackUp and Restore does not work with RAID configurations. You could try to restore the image to a Static (Basic) drive and it should work fine. That would tell you the problem is not with the Image, but with the RAID drivers.
Here is the scoop from the Acronic True Image 2013 user manual.
" Does True Image 2013 support RAID? - True Image 2013 supports hardware RAID arrays of all popular types. Support of software RAID configurations on dynamic disks is provided only with True Image 2013 Plus Pack. Even with the Plus Pack, the program does not support software RAID 1 (mirrored) and RAID 5. Acronis Bootable Rescue Media supports most of the popular hardware RAID controllers. If the standard Acronis rescue media does not "see" the RAID as a single volume, the media does not have the appropriate drivers. Owners of the True Image 2013 Plus Pack can try to create WinPE-based rescue media. This media may provide the necessary drivers.
Can I use True Image 2013 to migrate from a single disk to RAID? This is possible in many cases. However, it is better to use the backup and recovery method rather than cloning. If you recover a backup of a single disk to RAID, you will usually need to use the Universal Restore
feature provided by Plus Pack to add the RAID drivers during recovery. The drivers must have the .inf filename extension."
So I think it's a problem for even the high end retail products.
