I've had a few problems with Knoppix 5 detecting Linux software 
RAID arrays that were is a degraded state.

I had to load the RAID modules:
	modprobe raid1

And then start the RAID array:
	mdadm -A /dev/md0 /dev/sda1 /dev/sdb1

You may find that udev does not create the /dev/md0 device, in 
which case use /dev/.static/dev/md0 for the first RAID command.
