I had an external seagate 277N (from Hard Drives International) which
also would "chatter" or access the drive every 20 minutes or so.  It
would do this even if the Mac was off.  I called tech support and they
said that I had a bad bearing in the drive.  I sent it back, got a new
one, and this drive is quiet all the time.  (I don't turn the drive
off.)

If some of you are having hard drives which access themselves, you
may want to contact the company and see if the drive is supposed to
exhibit this type of behavior.
