Tested and Functional Logic Board
This PCB board 100729420 Rev B is confirmed to be in fully working condition. It was carefully removed from a functional Seagate Momentus ST500LT012 hard drive that had developed bad sectors, rendering the drive itself unreliable for continued storage. Before extraction, the hard drive unit, including this PCB, underwent HDD diagnostics using Badblocks software to verify the operational status of the electronics. This ensures you receive a component that has been tested and proven to work as expected prior to its removal.
Critical Compatibility Check for Your HDD
When replacing a hard drive PCB, it is absolutely vital to match the main board number, which in this case is 100729420 Rev B. Using an incompatible PCB can lead to further damage to your hard drive or prevent it from functioning altogether. This board is specifically intended for the Seagate Momentus 500GB model ST500LT012. Double-check your original PCB's markings, including "100729420 Rev B" and "C-14460240", to ensure a perfect match for a successful repair attempt.
Essential Firmware Transfer for Operation
Many modern hard drives, including the Seagate ST500LT012, store unique adaptive data or firmware information on the original PCB. For the replacement PCB (100729420 Rev B) to correctly interface with your hard drive platters and heads, this firmware must be transferred from your old, faulty board to this replacement. This typically involves desoldering a ROM or NV-RAM chip from your original PCB and soldering it onto this donor board. This step is critical for the drive to be recognized and operate.
Expertise Needed for ROM Chip Transfer
The process of transferring the firmware, whether it's by moving a ROM/NV-RAM chip or, in some cases, dealing with firmware located on the Main Controller IC, is a delicate operation. It requires specialized soldering equipment, such as a hot-air rework station, and significant technical expertise in electronics repair. Attempting this without the proper tools and knowledge can result in permanent damage to the PCB or the ROM chip itself. Please consider this before purchasing the PCB board 100729420 Rev B.
