Built myself a PC some time ago. Ran great for a few months, then it crashed several months back. Seemed clear that the HDD crashed. I replaced it. Windows installation wouldn't detect it. Checked BIOS and it couldn't detect it. Tried different SATA ports and cables. Still no luck. Thought maybe the replacement drive was DOA, so I replaced it again. Same story again. Replaced the motherboard, hoping it was a bad BIOS chip. Refurbished and updated BIOS motherboard came in with yet another drive. Still same story!!! I'm running ASRock A780LM motherboard and 160 Gb Seagate Barracuda.
oooooo i got an idea. Though I have never heard of this happening, maybe the power supply is not giving power to certain rails. If it has multiple rails i think it would be possible for atleast 1 to fail or to have an isolated failure. Tell us your whole rig.
Okay, this is a bit weird, but it might help me find some answers. It appears that my hard drives were all working fine when i received them. They all became corrupted when I loaded windows installation. I've now tried 4 drives, 2 different brands, all with the same problem.

There are many reasons when HDD is not detected by your PC.
Maybe you should change another port to connect the hdd, maybe the hdd is not enitialized - go to "disk management" and you will be able to enitialize it and it will be detected by PC.
Sometines it can be caused by virus that the master boot record is damaged then your hdd will not be detected.
