Forensic Duplicator Holmes 221B

The EZ Dupe Holmes 221B is a standalone forensic duplicator that clones one SATA source drive to up to three target drives simultaneously. It performs bit-for-bit forensic duplication at up to 300 MB/s, preserving every sector in a raw bit-stream format. A built-in write blocker prevents any modification to the source media when it is accessed via USB. Hash verification using MD5 and SHA-1 ensures the integrity of each copy.

Check Your Setup Before Ordering

The duplicator accepts 2.5-inch and 3.5-inch SATA hard drives or solid-state drives only; confirm your media uses a SATA interface. No host computer is required for operation, but a USB connection is available if you need to access the source drive with write-blocker protection. Ensure you have the appropriate power supply and drive trays or adapters for the form factors you intend to duplicate. The unit supports drives with bad sectors and will continue copying where possible.

Bundled Kit Changes

The forensic kit includes a durable carrying case that protects the duplicator during transport and allows it to function as a portable standalone station. Four copy modes and six erase modes, including Secure Erase and Enhanced Erase, give you flexibility for duplication and sanitisation workflows. Log files can be written to a destination drive for detailed work records and production status reports. Three copy functions cover disk-to-disk, file-to-disk and disk-to-file operations.

Questions about this item

Does the Holmes 221B kit include the cables and adapters needed to connect 2.5" and 3.5" SATA drives?

The Forensic Kit comes with a durable case and the duplicator itself, which operates as a stand-alone machine. You plug the source and target SATA drives directly into their respective slots without connecting to a computer.

Should I choose this duplicator for SATA SSD cloning or is it limited to mechanical hard drives?

It supports identical duplication of both 2.5" and 3.5" SATA HDDs and SSDs at speeds up to 300 MB/s, with forensic bit-stream copying and hash verification for either media type.

What does the 300 MB/s transfer rate mean when I am cloning a drive that has bad sectors?

The duplicator allows duplication to continue when the source drive has bad sectors, maintaining up to 300 MB/s (18 GB per minute) on healthy areas while skipping unreadable blocks during the forensic copy.
