I'm having Seagate Barracuda 1TB 2.5—inch Hard disk STlOOOLM048, 29172-500, SDMl, 100799274 REV A which suddenly stopped
working, upon examining and viewing your Youtube videos, I figured out that the Hard disk is not spinning and not clicking/buzzing sound.

I got a donor PCB with the same match, following the tutorial Video, I swapped the donor PCB With the BIOS chip of the Patient PCB.

The Hard disk started spinning with no clicking/buzzing sound but it is not detected even in Bios as well as Vlflndows Device Manager of 2
laptops both directly connecting it to the motherboard SATA port and even connecting via HHD SATA to USB Enclosures.

Please help me resolve this issue urgently as my data relating to some online submission is having a deadline approaching very soon.
