Q: Can you advise the firmware code of your board?

We can't confirm the firmware code with you. In most cases, you should move your original PCB's BIOS/Main Controller IC to the replacement board.

Q: Can you help me judge my HDD's problem is caused by PCB or not?

When a hard drive fails due to PCB failure, the drive usually cannot boot up or there may be an inaccurate display in the BIOS of the hard drive's information. Also power may not get to the hard drive and as a result it will not spin up.

Replacement the PCB will not solve the problem below:

Q: What does this mean "This PCB's BIOS is integrated on the Main Controller IC. You should exchange the Main Controller IC to let the HDD be recognized"

It means you should move the Main Controller IC (the biggest chip on the board) from your original PCB by using hot-air gun, and then solder it on the replacement board. Move the Main Controller IC is a complex job which need you have certain technique. Some electronics repair shop can do it.

Q:Why HDD can't spin after swapping PCB?

  • The BIOS will not be soldered well/The BIOS hadn't been changed.
  • The original HDD's electrical motor was been damaged.
  • The original HDD's heads-stack was dead

Q:Why the PCB board firmware (BIOS) transfer is a MUST?

We know PCB includes 2 parts: Hardware (components) and Firmware (data in the chip); The firmware includes HDD's unique configuration data. The HDD needs this unique configuration data to work. In order to have same circuit board firmware, we have to transfer the unique configuration data from the bad board to the good donor board.
