Who gives a crap what happens to the disk you're yanking?  If you pull the
correct disk, then you're saying it's crud anyway.  If you pull the wrong
disk, you're screwed whatever you do.

Face it, a perfectly reasonably failure of a disk could look exactly like
yanking it, so the PERC had better cope with it.

OS writes file to the PERC, PERC writes files to both disks, if one disappears
mid write, PERC copes.  If it doesn't, PERC broken.
