If you have an Apple IIGS systems with mixed-drive configurations (3.5" and
5.25"), you may find that when saving data under AppleWorks on the 3.5" drive,
both drive lights come on and the system locks up.
The Daisy Chain controller board in your 3.5" drive probably needs to be
replaced by an Apple dealer.
(NOTE: The 3.5" drive must be connected to the SmartPort, and the 5.25" drive
must be plugged into the 3.5" drive.)
