I have recently acquired an AE HD+ 3.5" drive. When plugged into my
IIgs it acts quite happily as an 800k drive. My understanding is that
the drive can act as a 1.6MB drive. I have installed the AE GS/OS
software for this but I see no way of formatting a disk as 1.6MB. This
is more a curiosity than a necessity, but would be interested to hear
from anyone with experience with this drive. The major advantage of
the drive so far is that my IIgs has always clicked continuously when
in GS/OS with the Apple 3.5 drive attached, it does not do this with
the AE drive.
