In preparation for sending my laptop in for repair, I used Ghost 9.0 to image my hard drive. After HP's repair facility reformatted my drive, I restored the imaged disk. Bad news though. My authorizations were not there. (Spectrasonics, Native INstruments, etc.) Looks like I have to redo them all.
I've Ghosted my drives and never had any issues with Native Instruments authorizations on restores or even Microsoft ones. Only time I've run into issues is with different hardware being replaced in the system.
