I was just asked a question concerning the sounds the internal
floppy drive in a Mac Plus makes compared to a SE. 

Upon start-up, or any other read/write operation of the floppy drive, 
when the operation is over a quiet hissing sound is heard before total
quiet. This seems to be distinct from the "chatter" of the heads.
I suspect it is the disk continuing to spin down for a second
before coming to a stop. In the SEs that I have listened to this
short "hissing" after the heads stop "chattering" is not present. 

The question is: Is this normal for the Mac Plus?  Is it due to different
software/hardware between the two machines?  Any help will be appreciated.
