How does one get a Gigabyte GA-990FXA-UD3 to detect SATA hard drives?

post #1 of 7
Thread Starter 
I recently got to work setting up a new rig with a Gigabyte GA-990FXA-UD3 rev4 (http://www.newegg.com/Product/Product.aspx?Item=N82E16813128514) motherboard and a 128 GB Samsung 840 EVO SSD, a 1 TB Westgate HDD, and an older 320 GB Westgate HDD. All of the drives are SATA and not a single one is detected by the motherboard. It is extremely unlikely that all 3 drives are failing at once, so the problem must be on the motherboard.

I have gone through every possible combination of settings in the BIOS’s SATA controller menu and have not gotten a single one to enumerate them. I’ve also tried every port, because it appears there’s a distinction between SATA ports 0-3 and 4-5 (0-3 have more features). All to no avail.

For a bit I gave up on the BIOS and went straight into my Windows 8.1 USB drive install. I provided the installer with all of the official drivers for the AHCI/SATA controller (downloaded from the manufacturer’s website) and that didn’t have any better luck.
I also briefly considered the possibility that the PSU isn’t delivering power to the drives. It seems unlikely since it’s powering everything else, but it may be plausible that a single line is misconnected or something. But sadly I have no way of actually testing this; my other computers are all laptops that don’t have exposed SATA ports inside of them (I checked). To confirm this I am ordering a multimeter (I need a better one anyways) and see if I can tie a small copper wire to the tip of the probe and then push that down into the power pin of the SATA power cable.

I’ve been troubleshooting this for about 2 days and it’s a real shame considering EVERYTHING else is working. I’ve looked around online for other folks having this problem and the solution they come up with always seems to be something akin to “kick the left tire twice, punch the steering wheel, and then turn the key”. I’ve sent a support request to Gigabyte but I don’t expect a speedy response.
It would be great to avoid RMAing this since I’ve already put a lot of effort into wiring everything correctly.

I greatly appreciate any help.

UPDATE: I can confirm that the hard drives are not even spinning up. A brief inspection of the cables showed no damage but I'm going to look closer.

I had a UD3 R3 that did that. Very frustrating.

First, have you set the hard drives to AHCI in the bios? If so, then I had to format a hard drive to get it to recognize it.

My second UD3 was an R4 and it found my hard drives fine. You might have a bad bios unless someone else can come up with a better solution.

Aye, the controller is set to AHCI.

But good idea on the bad bios. I'm gonna see if I can use this "Q-Flash" thing to flash a newer version of the bios.

No dice on updating the bios to V2.

You could burn something like GParted to a disk/usb to see if the motherboard is actually recognizing the disks, if it is, you might need to format them as miklkit said.

GParted on a USB stick is a really good idea. I'll give that a shot.

Lately I've been leaning towards saying that the PSU is faulty since they don't spin at all during the boot process. Probably gonna refund it and get a better modular one just to be sure.

Yup, it was the PSU. I replaced it and all is well. Thanks for your help folks.
