Why Has My RAID 0 Array Failed...AGAIN!!!??

[lettuce]

Ok got 2 150GB WD VeloceRaptors drives around the start of November last year, with in about a day of setting the array up i got the message from Intel Matrix Storage Manager that one of the drives on the array was failing and to backup info ASAP. I thought that it may have been a dodge install or something, so reformatted and started again.

This time it was ok for about 2-3 weeks until i got the same message again for Intel Matrix Storage Manager, this time i setup each drive as a single drive and ran diagnostic tests on both drives, all came back with 100% health and no errors.

So i thought 3rd time luck, its been around 2 months now since i reinstalled the RAID 0 array and all has been fine....until tonight!!! when Intel Matrix Storage Manager once again told me that 'one of the drives on the arry was failing'!!!

Why does the array keep failing its not the drives as they are all fine!, any suggestions??

Yeah both same drives. I did leave it last time, but then i started getting random restarts and sometime not booting into Vista

Very strange, have you tried disabling the caching and trying that? Might be the drive cache rather than the drive itself, is it always the same drive listed as having a fault?

Cant remember if it is the same drive both time, i'll make a note of it this time though! Where do i need to go to disable the cache again?

one or both drives need RMAing
or bad sata cable(s)
or bad sata ports

i've never had any raid 0 problems in 5 years

Well as i said im 99% sure it isnt the drives as ive tested the both with the WD diagnostic tool and they both came back fine! If it is a bad sata cable or plug, wouldnt the notification from the matrix manager be intermittent?

Hmm, not sure what to do, the first time i had this problem, my cpu wasnt OC then and was at stock!, so i dont think its an OC issue. I know i have the latest BIOS for my Abit Ip35-Pro. I guess i could jump back one BIOS update and see if that helps?, as i pretty sure its the RAID controller on the mobo thats the problem
