This is "normal" for the ZIP drive.  I'm not exactly sure why it doesn't 
answer the "mode sense" properly, but the geometry you end up with is the 
right one (96/64/32).  The solution is to ignore this error message and 
proceed.

BTW, I'd be interested to hear (off the mailing list) how successful you 
are with your ZIP drive.  I've had some trouble with mine, but it might 
have been due just to SCSI cabling problems and the like.  I'm just trying 
to keep a talley of how many people have succeeded/had trouble with ZIP 
drives.
