100724095 REV A PCB Board HDD Logic Controller for ST2000DX001 ST2000DM001 Specifications: Insulating Material: Organic Resin Board Number: 100724095 REV A Most HDD boards contain a unique BIOS (ROM or NVRAM chip) with specific data required to access the HDD system area. If the BIOS information is not compatible with your HDD, the drive's data cannot be read. Therefore, when replacing the PCB, it is essential to transfer the BIOS chip from the original board to the new one. BIOS chip swapping is required for proper functionality. Please Note: Replacing the PCB only addresses issues caused by PCB failure. Hard drive malfunctions are not always due to PCB faults, and this PCB is not guaranteed to repair your HDD. Attention: This item is not recommended for individuals without basic hard drive knowledge, proper tools (such as a hot-air station), or technical skills, unless they can access professional electronic repair services to assist with the BIOS transfer. We are only responsible for providing a fully functional PCB. Package Included: 1 x Hard Drive PCB Note: - Product details may vary slightly due to different manufacturing batches. Please consider this before purchasing. - Due to variations in display screens and lighting conditions, the actual color of the item may differ from the image shown. Thank you for your understanding.
