No because the Focus controller is an IDE controller.

Nope.  You can use IDE drives up to 2GB in size.  You need the
2.5" size to put the drive ON the card.  3.5" ones should work,
but they would need to be outside the IIGS in a separate case
to fit.

It is an IDE controller.

Not necessary.  IDE does not have termination of chain.  Drives
connect directly to controller.
