it's all about risk levels. The risk level of a power surge frying
everything in the box is higher than that of an IDE controller corrupting an
unmounted disk, &c.

To return to point zero, the risk level of filesystem corruption or an
accidental rm -rf damaging a soft mirror is relatively high. By the way, I'd
advise anyone using soft RAID on Linux to write a script that monitors the
state of /proc/mdstat, and/or use smartd. I've seen a number of soft RAID
systems fail to notify the administrators that disks had dropped out of
mirror until it was too late.
