P55-UD3R rev1 Killing Hard Drives?

Have you confirmed you are using the correct and latest chipset drivers from Gigabyte's website?

Have you confirmed if there is or is not a newer BIOS that maybe addresses a hard drive problem and updated to that one?

Have you run your tests using ALL of the ports on the board? Time consuming but might confirm one or more are bad.

Have you checked the Western Digital website to see if maybe your drives have issues which could be fixed by a firmware update? Seagate went through this last year on a series of drives.

Also, you will want to also check your RAM, all other connections to the motherboard (remove and re-seat everything firmly) and check the power output from your power supply (use the Gigabyte utilities to display the voltage output and see if you are getting power drop outs).

I had a motherboard a long time ago that corrupted my drives when I installed Windows (actually right after it was installed and I logged in for the first time - BAM!) and did indeed have to get rid of it.

I'm definitely using the latest chipset/BIOS and I know all the connections to the mobo are good. There also doesn't appear to be any firmware updates for the drive(s) available.

I checked the power supply voltages and didn't see anything out of the ordinary. Is there something I can run that will watch it over a long period of time?

I'll try swapping the SATA cables to other ports, but I may not notice any changes from that in a while.

Thanks!

Ah, interesting info. I'm currently using AHCI with my OS drive in SATA2_0, Data drive in 2_1 and DVD Drive in 2_2.

Before I set it to AHCI I did have it set to the old IDE compatibility mode, but thought I'd try AHCI. You guys think AHCI is worth it or not? I'm doing RAID or anything.

I, frankly, have failed to see any difference, but I've only tested superficially, and have been told my file mix is incorrect... (The comical thing is - I've been told my file sizes are both too big, and too small   by different people!) There is a fairly comprehensive piece here:

The main benefit I see is that I get 'hot-plug' capability on my AHCI eSATA port, but, as little as I actually use it, neither would it be a big deal to reboot when connecting something... Some people report some odd-ball problems using AHCI on various chipsets, but I've never tried to do a comprehensive search to see whether there are any commonalities - too lazy, and 'hands-full-enough', I guess  

been looking into this, because i'm experiencing the same problem.

we ( our company) have 25 maxdata favorit 300 xs core 2 duo systems.
they've been running for 4 years, never had any problems.
her the cronologic events:

* in one week, 10 of them started to break down ( harddrive fysical problems, bad sectors, disk missing etc/. etc.)
All those 10 systems broke down in a time period of 3 weeks., strange so many fail at the same time, but acceptable, they run all day, total poweron hours is around 10000 hours.

* i started replacing harddrives ( we had 3 2nd hand drives lying around, and one new one) , cloned the operating system from a working model, and placed them back.
* 2 of them broke down within a day again, bad sectors or unreadable disk.
* at an error check of the new drive i found a lot of bad sectors. , strange for a new disk, but no worrys, it can happen.
I ordered 8 new harddrives. started cloning again, and placed them back.
in the meantime i returned also the drive i mentioned, and got a replacement for it.

one day later i get 5 back with the same problems, all brand new disks broken.
still waiting to see if i get back a few more... But i do know one thing,
i can't explain why they are failing.

so far i tried 4 different brands, a total of around 15 replcaments ( yes i know , the above numbers don't add up)
i've been thinking about virus like activities, molistation by the users ( they are in a public library, where the public can use the systems)
faulty poweradapters, dirty electricity...

i really don't know.

For now i understand i do not need to attempt to rescue those systems. because the only result is, there will be more harddisks shredded.

What i do want to know, is why does this happen

ps. we have 3 locations in the building where we have those systems.. the failing systems are all from the same location, however there are on that location still 5 machines that work perfectly
