Seagate HDD Logic Board Replacement

This genuine PCB board, model 100387575 Rev D, is specifically designed as a replacement logic board for Seagate Barracuda 160 GB hard drives, particularly the ST3160812AS model. If your hard drive's electronics have failed but the mechanical components are still intact, this printed circuit board could be the key to recovering your valuable data or restoring your drive to full functionality. It's an essential component for hard drive repair and data recovery specialists, ensuring compatibility with specific Seagate drive models for optimal performance and reliability. Sourced from a working drive, it offers a cost-effective repair solution.

Key PCB Identifiers for Compatibility

When replacing a hard drive PCB, matching the board numbers is crucial. This board features the primary marking "100387575 Rev D" and may also show "100387565". These identifiers are vital for ensuring that the replacement board is a correct match for your faulty Seagate drive. Using an incompatible PCB can lead to further damage or prevent the drive from being recognized. Always verify these numbers on your original PCB before considering a replacement to ensure a successful repair attempt for your ST3160812AS drive or similar compatible models using this specific revision.

Target Hard Drive: Seagate Barracuda ST3160812AS

This PCB is intended for the Seagate Barracuda 7200.9 series, specifically the 160 GB model ST3160812AS. The compatible hard drive typically has a P/N (Part Number) like 9BD132-033 and firmware version such as 3.ADH, with a date code around 07202. These details help confirm that this PCB is the correct match for your specific hard drive unit. Ensuring these specifications align is critical for the potential success of the PCB swap, especially when firmware transfer is required for full drive operation and data access after replacement.

Reliable Tested PCB Board

This PCB board 100387575 Rev D is in fully working condition. It was carefully removed from a functional Seagate ST3160812AS hard drive that developed bad sectors. Before extraction, the donor hard drive underwent diagnostics using Badblocks software while connected to a PC. This testing confirmed the PCB's operational integrity, even though the drive's media was no longer reliable. This process ensures you receive a tested and working board, ready for firmware adaptation if needed, providing a solid foundation for your hard drive repair project and data recovery efforts.

Essential Firmware (ROM/BIOS) Transfer Explained

Many modern hard drives, including the Seagate Barracuda ST3160812AS, store unique adaptive data in a ROM or NV-RAM chip on the PCB. This firmware is essential for the drive to operate correctly. To use this replacement PCB 100387575 Rev D, you will likely need to transfer this chip from your original, faulty PCB to this donor board. This involves desoldering the chip from the old board and carefully soldering it onto the new one. This step is absolutely critical for the drive to recognize its platters and access data.

Advanced Skills for PCB Replacement

The firmware transfer procedure, which involves desoldering and soldering small electronic components like the ROM chip or sometimes the Main Controller IC, is a delicate task. It requires specialized tools, such as a fine-tipped soldering iron, hot air rework station, and magnification, as well as significant technical expertise and steady hands. Attempting this without the proper knowledge and equipment can lead to permanent damage to the PCB or the ROM chip, making data recovery impossible. Please only purchase this if you are confident in your abilities.
