Hard drive Seagate ST500LM000 chip problem

[eddygh]

I have a new HP notebook, and my Seagate ST500LM000 hard drive suddenly stopped working. The hard drive is completely silent and not spinning and not detectable even when connected externally using an enclosure. I thought the problem is the PCB board. I ordered the same PCB board and replaced it. The hard drive is spinning but not detected by the operating system. I swapped the bios chip, the hard drive is silent again and not spinning anymore. I recognized that the PCB was working but the bios chip is not working. My question is, is there a solution to repair the bios chip? Or the only solution is data recovery?

The best solution would be to send it for a data recovery specialist. But you can start posting here pictures of the "old" and the "new" boards.

The drive's model family is Kahuna. It is quite complicated models because of nand integration. Only high-skilled engineers can handle such cases. Address to people who know how to cook these drives ))
