This has always been a mystery, but does anyone know just WHY the Apple
IIgs's 5 1/4 drive -- the newer, daisy-chainable platinum-colored ones

incredibly loud "CHUCK-CHUCK-CHUCK-CHUCK-CHUCK" on bootup and the
"BRRRRAAAAAP" sound when GS/OS checks if there's anything in the drive.

The beige ones do that too. So does the disk ][, but not as loud. They're the same thing at different speeds actually - since the drive has no way of telling the system it's at head zero the system is forced to ram the head against the wall to make sure it's at head zero.

It always freaked me out as a kid.

Me too. :(
