Raiid keeps failing, Drives stop being detected

Velineon · 5 Jan 2010 at 18:33

Hey guys,

My raid 0 array keeps failing, and upon reboot one of the hard drives stops being detected by the bios and windows. I recently sent the hard drives back to OC and they have tested them and can find no problems. Im at an end and cannot find a solution to the problem.

I was told that it may be the intel raid drivers that may be causing the problem. Anyone got any info on this?

The hard drives are WD Velociraptors.

Any help would be great.

I had a similar issue just last week with my new SSD's, my RAID array kept breaking, and I ended up having to reinstall Win7 at least 8 times!!

After I removed all the power cables and SATA data cables and put it back together again everything has been perfect, so I'm pretty sure that it was a dodgy connection with one of my SATA cables, or my PSU power cables that was causing the problem for me.

Yeah i done the same things as you did. Reinstalled windows checked all cables, and they started working fine again. A week or so later the array dies again and one of the drives stops being detected. I then switched the drives to single usage, and again 1 of them stopped being detected by the bios and windows.

OCUK say there is nothing wrong with the drives

Dont know what else to do

You should maybe try replacing the SATA cables mate, one of them might be borked..

How long did OCuK have the drive, I've had intermittent faults that have gone undetected in a short test. You say yourself that the array can survive a week before it fails, so its going to take a long term test to prove the disk is bad.

As the drive fails for you in single drive as well as raid (and no bios detection) you could try moving the bad drive to a different sata port again, or even better to a different computer and see if it fails again, and then explain the problem to OCuK again and ask for more help/rma.

You could swap the cables over and see if its the same drive that fails next time.

Good luck.

Ive already explained it to them that it fails in a different computer and have moved the drive around and tried everything else. I also explained to them the problem would go away for a week or so and start again, but the punk on the phone didnt want to know. The guy on the phone thought he knew everything and was rude aswell.

They tested it for less then a day, and are sending it back to me and have charged my credit card £20.27 for re-delivery which i did not authorize. The fools.

Last time i buy from them.
