I was switching these disks around on a number of computers, and
altering partition tables, so I needed it. If I use raidstart, I get
interesting results:

raidstart /dev/md0 works without any trouble.
raidstart /dev/md1 gives lots of debugging info, and doesn't work. I
can't understand why it says 'hdi appears to be on the same physical
disk as hdi2' - and why it is referring to hdi at all.

Yes, that's a typo in the mail (not in the script, I could mount it just
