Thanks AJ, Thanks Dave.

I don't think I'm using multipathing : have no /etc/multipath.conf at  
all.

I thought I'd stopped dmraid, but it was still registering the drives  
it seems. I simply commented the dmraid startup lines out of /etc/ 
rc.sysinit and everything seems to be working how I want it to now.

There must be a nicer way of telling dmraid to leave things alone,  
but I couldn't find one and as this is working (and I'm not expecting  
to have to put a RAID on this machine in the future) I'm not too  
worried.

Cheers,
