I believe the disk accessing WITHOUT the drive light coming on is the 
onboard CACHE found on the Quantum's and other high speed SCSI's.

The reason why the front light doesn't come on is because the light is
connected to the actual controller card (in almost all cases) and
CACHE'ing is an internal function of the Hard Drive and thus the
controller has not initiated a transfer, therefore the drive light does
not come on.
