Question Why

[slaksono]

My Seagate ST250DM000 PC hard drive is not detected.
fortunately I have the same hard drive (type, motherboard series) and it works fine and I will use it as a PCB donor. But why did I transfer the BIOS chip to the donor PCB. hard drive still not recognized? Is it possible to replace the firmware bios chip on the hard drive or original BIOS chip? thanks.

Not sure exactly what you did, but the BIOS stays on the motherboard, NOT the hard drive. If your HDD is not being detected, try using a different SATA cable, a different SATA port on the motherboard, and try clearing the CMOS or updating the BIOS.

What are your full system specs?
