So just using the cheap dual dock for data transfer, no cloning. Second time in one year, two drives have been converted from NFSF to RAW when drives re-mounted after sleeping computer during long sessions. NO issues in my single USB 2.0 docks. I found several users complaining of same issue in the amazon reviews, so now I know i'm not alone. The Wavlink dock now in the landfill and looking for better enclosure.
