Hi guys,

Usually i can solve just about anything, but this thing makes me crazy.

Rig:

CPU: i7 920
MB: x58-UD5
Ram: 6GB
OS: W7x64 7600
260gtx
updated drivers and bios


Ok, now to the problem...
I have x2 f1 750 in raid 0 on ich10r for system and junk.
and x4 1tb black's on ich10r in raid 5 for storage. (yes 4 i know...)
The drives of the raid5 array randomly "ones a week or so" failing with "iaStor 9" error. (every time different drive)
I did all the test i can think of, but didn't find any thing wrong. And you know how long it takes to array this size to get back in shape....
I even tried to use second PSU dedicated for the raid 5 drives, with no luck....
Note: The raid 0 never had any problems.

I am not sure if any one here can pull a rabbit out of a hat, but any advice will be appreciated.
Thanks guys

what drivers did u used? or u didnt use any drivers ? I heard that raid0 on w7 you dont need any driver but raid 5 doest work that well without specific drivers, and since there is no official drivers for windows 7 this might be your problem.

Happy to help. I've been thinking of RAID 5 on ICH10 myself and worry about this same thing.

Hope you get it fixed.
