NO!  DON'T DO THAT!  AACCKK!

[Matthew is once again mortally wounded by a misprint.]

That's supposed to mean "Disk II".  UniDisks are absolutely, positively, under
no circumstances, supported in the IIgs *when conncted to Apple's UniDisk 3.5
Interface card.*

That card is *only* for the II+ and IIe, not the IIgs.  Get rid of the card
and plug your UniDisks into the disk connector on the back, and turn the
system back to Fast speed.  If you mix UniDisks with Apple 3.5 Drives, the
Apple 3.5 Drives have to be first in the chain.
