Seagate PCB Compatibility: Seagate PCB Swap Replacement Guide
1. Find a matching PCB for your fault Seagate hard drive:
To help to find out the right replacement pcb for your seagate hard drive, please advise the PCB number to us which is etched on the PCB, as the below photo. Make sure the number of 100466728.
2. Search 100466728 on HDDZone.com:
If you still can't find the PCB on our website or don't know which is your donor PCB, please feel free to contact us.
3. In most cases, swap Seagate HDD PCB is not directly change the fault PCB with the donor PCB. Should confirm the donor PCB should be adapted for the HDD.
Most Seagate HDD PCB boards have the BIOS (ROM or NVRAM chip) which includes the unique data to access the HDD system area. If the BIOS information is not compatible with your HDD, there is no way to read the HDD’s data. Because of this, we should use the original PCB’s BISO when we swap PCB.
BIOS is the 8pins (4 pins on each sides) with 25P05VP、25P10VP、25F512、25F1024、25F1024AN、SST25VF512、SST25VF010, etc.
How to change Seagate HDD PCB BIOS?
You can move the BIOS from your original PCB by using hot-air gun, then solder it on the replacement board. Or you can find the electronics repair shop to help you.
If there is no BIOS on the Seagate PCB, it means the BIOS is integrated on the Main Controller IC
You should exchange the Main Controller IC to let the HDD be recognized. Move the Main Controller IC (the biggest chip on the board) is complex jobs which need you have certain technique. Some electronics repair shop can do it.
