Does anyone know if Vista Complete PC Backup makes a copy of the whole drive or just the used disk space, as I have recently reinstalled my PC Complete Backup and need to recover some files from the free disk space.

Hopefully i still will be able to recover my files?

I am sorry, I'm afraid Vistas backup only does file backup and then incremental ones, and not a sector based backup, but never the les you may be able to find the lost files in the previous free space, since the restored image tends to occupy the same space, hence the free space tends to remain untouched.

Thanks I have run a file recovery program and unable to locate the deleted files, so maybe Vista backup does not restore back to the same disk sector?

Oh no it is NOT sector based so it won't, I just noticed with my system since I keep it defragmented it tends to stack all data from bottom to top, so any info in the free space might be recoverable since it wasn't written over.
