RAID 0 Volume 'array' is in a non redundant, failed disks state
I am concerned that one of my Hard drives is about to fail but on the contrary my PC is booting and performing as quick
as it ever has and my understanding of RAID0 is that if one Hard drive fails I would not be able to load windows.
Can anybody explain the error messages detailed below.
I have a Dimension 9150 Intel 940 Dual Core 3.2 GHz , 2 GB DDR2, Windows Xp Media Centre.
500GB (2x250GB) 7200rpm SATA Hard Drive-Dual HDD cinfigured as Raid 0 Stripe
In boot I get the following message before Windows is loaded
RAID Columns
ID Name Level Strip Size Status Bootable
0 Array Raid0(stripe) 128 KB 465.7 GB Normal Yes
Physical Discs
Port Drive Model Serial Size Type/ Status(vol ID)

2 WDC WD2500JS-75N WD-Wmank 232.8GB Error ocurred(0)
When I perform Check Disc the discs are fine

Windows has finished checking your disk.
Please wait while your computer restarts.
If I look at the event log I get the following warning
RAID 0 Volume 'array' is in a non redundant, failed disks state

Hi spanfree,
This is the proble with RAID 0. High risk. You didn't say but I assume you've got your important stuff backed up.
I would immediately start planning to replace the drive and reinstall XP. Alternately, you could install on the good drive. If you did not receive an XP disc with your system, go here to order one.

I would follow Osprey's good advice. Windows can only see the virtual drive that is formed from the two physical hard drives, and the RAID ROM uses an error correction algorithm that can fix up to a certain number of errors. Chkdsk will only check the virtual drive and so does not see the actual output of the two hard drives. Only the RAID status screen and the Intel Matrix Storage Manager application will show you the info on the physical hard drives.

I am not an expert but the 'RAID columns' indicates a 'Status' of 'Normal' so that's why you can still boot. A status of 'Normal' should indicate that there are no issues to worry about.
But in your case, you have conflicting information. Possibly one of the HDDs is predicted to fail or there is possibly some fault with the Intel Rapid Storage Technology, RST, drivers and/or HDD firmware when fetching some data from the HDD.
Unfortunately the Intel RST application i have on Windows7 does not give me access to the raw HDD SMART data so likely you also will not be able to view this data yourself. In any case, I had understood that if some of the SMART data predicts a HDD failure, the 'Raid Columns' 'Status' should be changed to 'At Risk'.
Also, when a Status is 'At Risk', with Raid 0, you could simply plug in another WDC WD2500JS-75N HDD and define it as a 'Spare' drive. In such cases the RAID drivers will automatically rebuild the 'At Risk' HDD data to the 'Spare' HDD and then bring the 'At Risk' HDD offline. But for this to work, the 'Status' needs to be 'At Risk'.
As a first step in fixing this issue, i would make a complete system backup.
Also, it may be that Western Digital has some bootable application that you can use to interrogate the HDD SMART data and see if there are any issues to worry about. But make sure you back up your system first as you may loose data sooner than later.
Other things to consider is that there may be a firmware update for your HDD's, a driver updates for Intel RST, etc. But backup first or risk loosing data sooner rather than later!

Thank you all for your help. Yes I have all my personal stuff backed up and will order a new Hard Drive today. I need to order the XP discs as well but as I am in the UK I think it must be a separate link so I need to do some searching. I will then have these to hand before I do some tinkering
It's a shame because as I mentioned the system is booting faster than it has ever done only taking about 60 seconds.

Sorry, I should have mentioned that link is only for the US. In the UK, you should be able to call customer service to get the discs.
