I have 2 older machines which are used for non-critical work - both use Gigabyte GA-MA790GP-DSH4 mobos. I built both of them about 18 months ago and each has been in continuous service ever since with not a single problem. (background - I have built well over 100 systems (for myself and at work) in the last 20 years and have a fairly high degree of tech savvy)
Recently I wanted to add a second 1TB sata drive to one of the machines, and I got an especially good buy on a WD 1TB drive - although it is sata3, not 2. The drive runs fine as a sata2 drive in another machine that only supports sata2 (tested AFTER the problem first happened).
I shut down, put it in one of the two boxes with the GA-MA790GP-GSH4's, and then rebooted. The machine previously had 2 sata2 drives and 2 sata dvd burners in it and had no problems. When I rebooted with the sata3 drive in it, the bios saw NO sata devices - period.
So I removed the sata3 drive and rebooted - the box still did not recognize its sata drives.
I suspeted a bios problem (it had the original F1 bios in it) and so I flashed the bios upgrading it to F6. The upgrade ran fine and the machine came up successfully showing the new bios. However, still no sata drives recognized. I have tried every trick I know and I cannot get it to locate any sata devices. (IDE/PATA works just fine - but that doesn't help.
I removed the drive and rebooted - and still no SATA drives are seen. After testing the sata3 drive in another box. with no problems, I put it into the 2nd machine with the same mobo, and it, too can no longer recognize any sata drives.
It isn't a matter of recognizing what's on the drive(s) - the drives are not seen at all.
Currently I'm stumped. Any suggestions would be greatly appreciated.
