I recently purchased 2 Seagate ES.2 750gb drives. The problem I am having is that the first hard drive is not detected initially. If I restart the computer (either with a hard reset or by going into the BIOS and then exiting so that it goes through the POST process again) it is detected fine.

I have tried changing the power cables and sata cables. I have also reversed the order that the drives are plugged in. It doesn't matter what I do, the hard drive that is plugged into the lowest SATA slot is not detected. If I go into the BIOS and do an autodetect of the hard drives the first drive shows up as only 136gb. I have also tried plugging a third hard drive (also a Seagate, but an older model) into a SATA slot ahead of my ES.2 drives and the old drive is detected but the first of the new drives is not.

I have tried flashing the BIOS to the newest version but that hasn't fixed it. I am assuming this is a motherboard issue because it doesn't matter which drive, it only seems to be affected by the order in which they are plugged in. I looked at the SMART data on the drives and I don't see any problems. Needless to say, unless I remember to restart the computer every time I turn it on this is wrecking havoc with a RAID setup that I wanted to use. Does anyone have any suggestions for how to fix this?

My motherboard is a Gigabyte GA-M57SLI-S4 (rev. 2.0)

Just guessing...

If you have a RAID 1 setup...one of your drives will "disappear", since the combined drives are only seen as having the volume of one drive (of the same size).


But...that doesn't account for what happens on reboot.

Maybe that BIOS flash was uncalled for, but...the BIOS settings are where I would look.
