True, but those failure modes are much less common the a media failure or head

That brings me to another point, though -- if you had 2 seperate disks in the
same enclosure, with no environmental isolation between them, you'd likely
kill both disks with a head crash on either one. A head crash in a modern
high-speed drive tends to throw a lot of pulverized platter and head bits
around inside the disk, damaging the other platters that may not have been
involved in the actual crash. So I think you'd need to isolate the sections
from each other with some kind of airtight (or at least
really-small-bits-of-metal tight) seal; probably doable, but would take up
more room that you're pretty low on already.

That sure would make an interesting drive :) If it could be pulled off cheap
enough, it would be well worth it, too.
