Data Recovery Phase

Task created in DE to clone drive onto another working hard disk drive. Task completed with a minimal amount of unreadable sectors, mostly early on the drive. Primarily only OS and system files appear to be affected. Plus there were a few bad sectors in the MFT (master file table) causing some folder structure corruption. However the corruption seems to be minimal and isolated to areas mostly containing Windows system and program files which are not likely to be missed by the customer. All user data appears to be in good shape.
