All the time (I'm pretty sure that is broken on this system, because I
can usually hear the drive spin up or the arm movement anyway).  The
problem seems to be though, with all that stuff in memory, that my main
memory (only 256M on this machine) is pretty filled up.  And I think
that 256M of OS and X is just way the heck too much.  

I really don't want too much going on, just X and its requriements, The
Kernal, the print stuff, the USB stuff and the CD and DVD.  So what is
with 104 processes.  Even Windows only shows 54 on my XP box, and I
thought Windows was a HOG.
