I believe he meant power it down after it had powered up. Once it gets a
START UNIT, it stays STARTed. He (and I) need a way to give a STOP UNIT
after a certain length of idle time and automatically make sure the device
is ready when trying to read (ie, send a START UNIT before reading). This
would delay the initial access, but reduce drive wear from idle use. I'm
guessing this would take a kernel modification, much like the APM BIOS stuff
for the x86s (except without the BIOS).
