I have an old machine, please have pity on my soul and send me new
stuff ;-)

This is a Wyse 3216 with an old WD controller and a Micropolis 71MB
drive.  It took 64 seconds :-(.  I could hear the heads stepping
off and they were going about as fast as I've ever heard them go
while actually doing anything, so I feel comfortable that 64
seconds is a fairly minimum amount of time for a 100KB block size
on this piece of hardware.  I am running 2.2.3 and had to write a
little C program because "dd" wouldn't take 100k as the block size.
