Engineered to match original Samsung specifications, this PCB features the S3M_329_REV.01 R00 board layout and BF41-00357A part number, ensuring full hardware compatibility with your faulty drive. It supports the M321HX/VP4 model family and other Samsung HM-series USB external hard drives.
Critical Note: For operation, transferring the 8-pin BIOS/ROM chip from your original PCB to this replacement board is MANDATORY. This step retains unique drive firmware. This replacement fixes electronic failures only and will not resolve mechanical issues (e.g., head crashes, motor failure).
