Hi all,

I have seen several threads about HDD's failing but I can't seem to find a solution. I'll provide a very detailed explanation and will include the most minor of details.

Below is a summary of my build:
Motherboard Name Gigabyte GA-970A-DS3
CPU: AMD OctalCore AMD FX-8350, 4128 MHz (20.5 x 201)
VIDEO CARD: NVIDIA GeForce GTX 550 Ti (1 GB)
RAM: Patriot Memory 1866 CL9 Series 4 GB DDR3-1600 DDR3 SDRAM (x4)

HDD'S:
OCZ-AGILITY3 ATA Device (SATA-III) (For OS - Windows 7 Ultimate 64bit)
Hitachi HDS721010DLE630 ATA Device (1000 GB, 7200 RPM, SATA-III) (I have three of these but unplugged 2)**************The problem I am having is with these 3 specifically.
WD My Book 1140 USB Device (931 GB, USB) (EXTERNAL DRIVE)

POWER SUPPLY Thermaltake TR2 TR-600 600W ATX12V v2.3 SLI Ready CrossFire Ready Power Supply

So, it all started with just 2 of my Hitatchi Drives. They would disappear from Windows and come back whenever I restart PC. Eventually, I used tools to check SMART status. (AMD tools, HD Tune, Crystal DISK Info), and found reports suggesting the HDD"s have gone bad. So, I RMA'd those two.(Third one has never given me any of these issues). Replaced the 2 drives, things seemed okay for a few weeks, where the problem repeated itself again with the 2 Drives I had just replaced. This time, they disappeared, but SMART status was fine, performance tests suggested those drives are fine. I figured maybe a power issue so I plugged those two for now. A week later with the two unplugged, the third one is now experiencing these problems, and SMART status changes from bad to good regularly due to a fluctuating seek error rate. Reports are healthy at 100 Seek Error Rate, but bad once it drops to 65 - Never goes below 65.

Clearly something is destroying my HDD's?

What I have tried so far:
- Reinstalled Windows (very long shot)
- Updated BIOS
- Replaced HDD's
- Tried different power cables for HDD's.
- Switched Ports

Is it my PSU? Bad MOBO?

sounds like your sata controller is failing.

when you switched ports, did you switch to a different sata controller? mobos often have 2.

if you dont have a second sata controller, you may need to buy a pci based one.

Thanks for the immediate response. Yes, I tried switching to a different controller to no avail. I just asked a techie at a computer store and he also told me hands down it's the SATA controller. The question then is, does that mean my HDD's are fine and if I replace mobo, I'd be able to use them again or do they need to be replaced too now?

Also, I was going to look into my mobo to see if it's still on warranty and have them replace it for me, but are you suggesting that I shouldn't go for the same mobo again?

Cheers!

that should clear up the problem. the hdds should be fine, assuming that the problem is the controller. i doubt all your hard drives are giving the same problems.
