How To Swap Seagate Hard Drive PCB Boards

When the Seagate HDD damaged, many people don't know the problem was caused by HDD's hardware corrupted or PCB corrupted. Now we will do a simple description here:

HDD can't spin up. Either no sound or a short, quiet tickling sound can be heard; A burning smell can be sensed coming from the HDD or PCB; Burned components on the PCB; PCB's interface damaged. All the problems are caused by PCB corrupted.

In other cases, HDD's problems are unlikely caused by PCB. Such as HDD PCB was very hot; HDD can spin, but can't be recognized; HDD be recognized slowly, etc. When you swap PCB, you need to know your Seagate PCB's board number. For example:

The number in the green circle is the board number

This PCB's board number is 100475720 REV A. In general, Seagate PCB's board number begins with 100***, end with REV A, B, C, etc. Most friends think the two-dimensional on the white label as the board number.

When you get the donor PCB, you need to move your original/damaged PCB's BIOS the donor PCB. Suggest using the hot-air gun. If you can't do it by yourself, you can find a cell phone/computer repair shop help you. Most Seagate need to be changed the BIOS.

Changing BIOS note:
Move the BIOS from your original PCB by using hot-air gun, then solder it on the replacement board. Please note when you change the BIOS, you need to confirm the BIOS orientation. Otherwise, the BIOS will be burnt. Also you should confirm the BIOS be solder firm.
