Does a mirror setup really cover anything else that if a drive
suddenly dies?
Slow corruption gets propagated to the mirror disk, doesn't it?

There's nothing the system can do to me that I haven't done
much more efficiently already ;-)

I leave the U160 disks on one channel.
My future u320 disks will occupy the other one.

Moved the cable to channel A, where it should been in the
first place. Shouldn't matter if I boot ftom mpt0 ot mpt1.
Changed a setting in the controller BIOS to disable RAID.
Have changed that back and reinstalling DFly.
Just rebooted, works fine.

And changed them back. It still works.
Want me to test some more settings (as long as it's not any RAID stuff)
