I guarantee you that there are a number of controllers which have
different ideas of how to do soft sector sparing _at the controller
level_ rather than at the drive level.
Disks created with such controllers aren't portable, since they
depend on controller state information, which may not be valid
from controller to controller, depending on the controller settings
(I killed a disk by not having the WD1007 soft sector sparing
jumper set the same in the machine I put it in as in the machine I
took it out of... 8^)).

Yeah, we should pick new magic. It's bound to die again in the future,
though, once "what's magic" changes out from under us again... 8^(.
