I can't SWEAR that this is the problem, but it will break sooner or later..

If you're going to use RAID on the disk, the first partition MUST start
on block 1 (one!), not 0 (zero). Can't remember exactly why (usually I
forget 'obvious reasons' :) but it have something to do with with ext2/3
inode list, the boot block or with the RAID system needing block zero for
something...

As i said, can't remember exactly (google if you must know), but I know
that every time I forgot (I don't forget any more :) this, I've been bitten.

Try repartition the disk... You'll loose whatever's on sd[ab]1...


NOTE: This is true EVEN if the first partition isn't an MD!
