As an exceptionally powerful and useful hardware tool, this standalone hard drive duplicator turns what used to be a daunting and complicated task into a simple push of a button! Any 2.5" or 3.5" SATA hard drive or SSD, with any operating system, disk format, or file type, can be duplicated without a computer connection or any advanced computer skills. If the original drive was bootable, the copied drive will be bootable. Hidden files, system files, applications, license keys are all copied intact. How can this be so easy? The Retriever simply makes an exact copy of every block sector of the source drive to the target drive. If the target drive is larger than the source drive, the extra capacity can be assigned to another partition. The Retriever can also be connected via USB 3.0 to your PC or Mac when not duplicating drives.
