Q: Can you please let me know which board I need to order for this disk.
Head and motor are ok, it’s an electronic issue. If I replace the board, I still need to move the ROM ? Or Can I just order a board, swap it and it will work ?
A: https://www.hddzone.com/wd1003fzex00k3ca0-wd-pcb-2060800039001-p-2757.html is your donor PCB.
The BIOS need to be changed. You can move the BIOS from your original PCB by using hot-air gun, then solder it on the replacement board. Please refer: http://www.datarecoveryunion.com/hard-drive-rom-chip-swapreplacement/. Or you can find an electronics repair shop help you.
