   Can SCSI Saver interfere with partitioning software??  Good question.  I've
never had any problems with it, and I've never had any of my friends attribute
anything to it.

   My setup.  One original Apple internal 40 Mb drive, one external 180 Mb
drive partitioned into a 40 Mb and a 140 Mb.  The cdev works by checking for
SCSI devices on the chain.  You can select which, if any, spin down.  It will
spin down an entire drive, so you can't take down just partitions (most people
could guess this already).

  The concept doesn't seem too complicated to me.  Look for a given period of
inactivity, send the drive a "sleep" command after it, and then a wake-up call
if anybody needs it.  I believe these are Macintosh "standard" commands, so I
can't imagine a Mac drive not responding to them.

   If I recieve any feedback pro or con when the people who have asked for it
start using it I'll post here.
