Hi guys,

Powered my PC down this morning - no issues. Powered it back up and it wouldnt boot. Then I realised one of my 750Gb WD Black Series drives was showing as 'Failure(0)' in the Intel RAID bios.

Any ideas why this has happened and if its recoverable?

Thanks/

Is the PC POSTing as far as the Intel RAID BIOS, showing the failed drive in red and just stopping?
 
I'm not concerned about the fact I've lost my Windows install.

What I'm trying to do is work out what has happened and why its happened. Is pretty much the only outcome here a drive failure?
 
The drive in question is a WD7501AALS-00E8B0.

It was purchased as a WD Black Series.

OcUK have a Black Series but it is a WD7502AAEX.

What is the difference between the two drives and can I use the newer one as a replacement? I beleive the other drive in the array is also an AALS.
 
Hmm, WD do an Advanced RMA. This is probably the way forward. Trouble is I am not home until Tuesday and wish to get the ball rolling. All I've had so far is the error on the RAID Bios.

Is it certain the drive has failed? Is there anything else that would cause this? I don't want to set up an advanced RMA unless I am certain I have a failed drive, but I cannot test it until Tuesday :(

The error message on the RAID BIOS is 'Error Occured (0)'

thats pretty much the long and short of it there mate

i gave up on raid 0 a long time ago on mech drives.

on SSDs its a lot better. but in fairness it really isnt worth the hassle.

i would go single drive tbh

have you got an SSD yet Fox?
 
I really hate RAID0 even if its just an OS drive. In my eyes it offers VERY little bennefit.

*Doubles hardware issues.
*Doesnt increase speed to warrant risk.

I run 1 disc for OS and apps. and 2 discs for media/documents in RAID1.
 
Hi guys,

Back home now. Turned the machine on - Error Occured. But Windows booted perfectly. Once I was into Windows the Intel Storage Manager popped up to tell me one of my discs had failed, was not accessible and all my data was lost.

In reality, everything is perfectly accessible and working fine - except for the fact it's reporting this error.

Any ideas what is going on here?

What does 'Reset disk to normal' do in the storage manager?

What it says on the tin. It resets all failure and warning flags on that SATA port, and gives you (what would appear to be) a fully functioning array again.

Just FYI, it might not be the drives at all. I've got a machine at work that at least once a day it decides that a disk has fallen over (RAID1), on an Intel ICH10R controller (onboard on an ASUS P6TSE), nothing wrong with the disks at all.
 
Well it's all gone wrong again - it wont boot now - back to showing 'Error Occured'.

Still, managed to save the few files that were not backed up in the random period it did work.

It boots past the RAID bios screen but sits on the Asus motherboard splash screen immediatly after.
