Foo, one problem I see is pulling the power connector off of the
drive. If the ground pins disconnect first, it's bye-bye drive.

For a garden-variety setup, the IDE interface on the motherboard 
_might_ tri-state all the active lines, but if the ground pins on 
the signal cable disconnect before the write line, the resulting 
floating ground-reference on the drive could be very troublesome.

For example (from experience) it could write random garbage to
the platters while moving the heads to track zero, effectively
nuking every track on the drive. This could also occur when plugging
the new drive in. 
Bottom line: I'd look around for products that claim to have solved 
this issue, I'm guessing it's pretty tricky. But great capability 
if/when someone solves the hardware issues.

will always be useful and which never will grow dim or doubtful. -- Mark Twain
