Bios Does not see Sata HD
I have a computer with 160GB HD which I assumed failed because computer bios quit recognizing it so I swapped it out with a 80GB HD reinstalled and boom it booted and ran like a pro. I got up today to find the computer become unbootable again and I noticed It wasn't detected. So I kinda wondering if the sata controller is destroying my harddrives so I put the harddrives in another system and they boot just fine. So my issues is now is getting the bios in the other computer to recognize them and what could be causeing this. I reset the bios and removed the battery as well. So what do you think?
