This NAS from WD, does it use Linux's software RAID?
If not, you can't assemble it under Linux, because the RAID controller
is using proprietary methods.

I've contacted just about everyone that knows a thing about RAID5, but no
one is really able to help me. Anyhow I've read up a lot on RAID5 arrays and
how to properly assemble them. However I've run into a problem with a NAS
system from WD that I just can't seem to figure out.

I have a ¾ disks in the array, 1 went down and is out of commission.  I've
been able to assemble my array through mdadm using --assemble --scan. However
I cannot access the array due to the fact that the array cannot read a
filesystem. Everytime I try to mount I get mount: wrong fs type… etc. I
know that the FS is an ext3 FS. However I cannot seem to get this
thing going. I was wondering if anyone could point me in the right
direction with this. I can't seem to find anyone that is capable of
solving this. I would appreciate any help. Thanks!

What's the output of 'cat /proc/mdstat' after you assemble the array?
And what exact error (and dmesg output) do you get when trying to mount
it as ext3?

Cheers,
