Drive 0: failure detected...

[rgoggins]

Hi all,

Firstly here's my config...

=======
MacPro4,1
x2 Quad-Core Intel Xeon 2.93 GHz
Intel X25-M 160 GB SSD (startup disk - second optical bay)
Apple Raid Card
x4 300 GB VelociRaptor - WD3000HLFS (Raid 0 set - 1.2 TB)
Quadro FX 4800
16 GB RAM
=======

Now, to the issue...

When I start up this Mac I receive the following error via the Raid Utility...

Drive 0: failure detected - Previous drive status was unassigned

The Raid Set is not mounted and one of the VR drives are not displaying within the set. I can also not mount the Raid Set at this point.

So I then clear the event within the Raid Utility and I then restart the Mac and all is good. No Raid errors, the Raid set (volume) is mounted and all 4 VR drives are present within the set.

There is no data loss on the Raid Set and the cycle continues.

Basically, I have to go through this procedure every time I startup.

Anyone ever seen this Raid error before? Any ideas?

Cheers,
Rob

What's the SMART status on the drive?

And normally I'd say just swap out the drive, but seeing that your drives are in RAID 0, I'd say back everything up and then restore the array after doing a drive swap.
