disklabels tend to be machine dependent so I suspect thats your problem.
I'd suggest either

a) using something like a DOS file system (access with the mtools package
   or just mount -t msdos) or HFS files system (access with the hfsutils
   or xhfs package).  

b) use tar.  for example

        tar cvf /dev/rsdXc file1 [file2 ...]

   to write and 

         tar tvf /dev/rsdXc

   to list and
 
         tar xvf /dev/rsdXc
  
  to extract.  Be _sure_ to replace "X" with the correct number for your
  zip device.  Do _not_ mess up and use the number for your hard drive or
  you'll be sorry.
