   I won't argue the merits of turning the drive off and on excessively, except
to say that the actual drive mechanism is sealed air-tight and booting up and
down cannot draw air into it.

   What I can say is that there is a way to power your HD up and down without
shutting off the Mac.  I have a control panel device called SCSI Saver that
was written and distributed to the public domain.  You throw it in the system
folder and then set the number of minutes of non-disk access until the drive
is to be spun down.  The drive will automatically come up to speed when access
is requested (but it takes about 20 seconds more).

   I'll be glad to mail it to anyone who wants a copy.
