Ah. Sorry. I didn't realise I had only mailed you directly.

Yep. That's basically what I do but I partition the disk and format the partitions for Linux raid autodetect and set one of the partitions as bootable. Then, as you say, I just add them using mdadm.
I've resorted to reproducing my setup using vmware and seeing if I can reproduce the problem that way. Hopefully it will help shine some light on the issue.
Thanks very much for your time,
Matt
