StarTech.com duplicators were not designed to recover failing or damaged drives. If the duplicator encounters a corrupt or unreadable sector, the duplication halts and fails. If the source drive has bad sectors, use the Read Error Skip feature if your model of duplicator has it; however, if there are too many errors, it may still halt and fail even with this feature. If this happens, you will need third-party recovery software or custom-built recovery hardware to copy from a failing or damaged drive.
