I am not too happy, I bought this to make my Vista "D" drive bigger by taking free space from my "C:" drive that is very large. The system went through the reboots, I received no errors of any kind, yet it did nothing....drives are still the same. So I thought, ok try from the bootable CD as was suggested in another thread. It boots to the CD just fine, but the software doesn't see my hard drive....I am running the latest version. Needless, to say I am not a happy camper at this point.
