Not that I am aware of...  I have 2 ZIP drives which have been connected
to various systems and worked happily.

The disktab entry I use is 

zip100|iomega100|iomega ZIP 100 96Mb:\
        :dt=SCSI:ty=???:se#512:nt#64:ns#32:nc#96:\
        :pa#16384:oa#0:ba#4096:fa#512:ta=4.2BSD:\
        :pb#16384:ob#16384:tb=swap:\
        :pc#196608:oc#0:\
        :ph#163840:oh#32768:bh#4096:fh#512:th=4.2BSD:   

You might want to play with the partition layout somewhat.  The above
was sufficient to create a bootable FreeBSD disk!

For the Jaz drive, just make the number of cylinders (nc) bigger to get
the right number of 512-byte blocks.
