I bought this motherboard to switch out a suspected intermittent faulty ASROCK mobo (sometimes the computer freezes or bluescreens - GFX card and RAM were replaced, HDD was erased and Win 7 was freshly reinstalled with no fix, Linux on USB stick was run and still got some crashes in that environment).

So to be clear the HDD runs fine with the ASROCK. It's a Samsung HD103SJ 1TB.

I disassembled the computer, put the new board in and rebuilt the computer. The computer POSTS fine but it only recognises the DVD drive on SATA. The HDD isn't shown. I tried it without the DVD plugged in, no luck. I tried the cables from the DVD drive on the HDD, no luck. I altered the options between IDE and AHCI in the BIOS, no luck. I changed hot pluggable in BIOS on and off, no luck.

I listened to the drive and heard it was not spinning up. I disconnected the SATA cable but left the power cable in and then it would spin up on powering on the computer. But with the SATA cable connected it won't spin up. So I tried it on another SATA port and powered on, this time it made some horrendous clacking sounds and the HDD LED stayed lit on the computer. I was worried now that the HDD had a fault or was damaged (see later - it isn't).

I changed all the options in the BIOS to "power down" on every SATA port. Rebooted. Naturally then nothing was recognised in BIOS but the drive did spin up. So I entered into BIOS and changed all the SATA ports to "power enabled". Save and exited BIOS and the computer boots into Windows. Hard drive worked fine and no data problems. Shutdown the computer. Turn on. Hard drive not recognised again! I checked Gigabyte's website but there is no BIOS update for the board.

Took the computer apart, put the old motherboard back in and rebuilt the computer. Everything working fine and hard drive spins and boots up as expected, no strange noises.

Any ideas? Looks like I am going to have to return this Gigabyte motherboard. Maybe I should buy an ASUS. I can't spend more hours trying my luck with another Gigabyte board.

So I bought an MSI 970A-G43 and had the exact same problem. I believe there could be an incompatibilty between the AMD 970/SB950 chipset and the Samsung HD103SJ 1TB hard drive.

Final solution: I bought an older model motherboard with an AMD 760G/SB710 chipset (an Asus M5A78L) and it works fine. (The original ASRock motherboard had an AMD 790GX/SB750 chipset).
