The 100721570 Seagate PCB repair process can usually be divided into 2 steps: find a replacement PCB and firmware transfer.
100721570 Seagate PCB: Board Number
Finding a donor Seagate PCB board is easy, you just need to open the hard drive and find the board number like “100*** on the board. The following picture shows the board number of 100721570 Seagate PCB.
100721570 Seagate PCB: BIOS Chip
The BIOS chip on the PCB board is very easy to find. The 8pins chip is the BIOS chip. If the chip is not found on the board, you need to exchange the main chip (the largest chip). The following picture shows the BIOS chip of 100721570 Seagate PCB.
.
BIOS chip holds unique data (firmware) required to access the hard drive system area. If PCB firmware is missing or incorrect, there is no access to the hard drive, and no access to user data, so the process of BIOS chip repalcement is also called firmware transfer.
PCB Board firmware transfer tool: hot-air gun, tweezers, screwdrivers
