Have you actually tried using it without the "scsictl sd1 start"?  It should 
be spun up automatically.  Even if it's not, issuing the START command and 
then reopening the device should work fine.

In addition, most drives have a jumper that you can move to cause them to spin 
up automatically when power is applied.
