Ever since my move (breaking down & hooking up)
my G4 2002, every time it enters Sleep Mode
even though the Display goes blank, I can hear
the HardDrive running full on... but when I press
anykey or move the Mouse to view the Display
it remains blank (black) and nothing responds,
forcing me to do an illegal Shut-Down/Restart
to return the G4 to normal.

Lather/Rinse/Repeat every time it goes to Sleep,
whether it times-out thru Energy Saver, or if
I select "SLEEP" through the Apple Menu. frown
