Yes, that worked fine, thanks a lot.

Now a question - why is is that a UFS formatted ZIP disk gives me so much
less storage space than a DOS one? Here's the ouput of df for the two
disks, both empty:
Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/sd0s4 98078 0 98078 0% /zip
...
/dev/sd0 92607 0 85198 0% /zip
I formatted the UFS disk with "newfs -T zip100 /dev/rsd0c" which I assume
takes the following from /etc/disktab:
zip100|zip 100:\
:ty=removable:se#512:nc#96:nt#64:ns#32:\
:pa#196608:oa#0:ba#4096:fa#512:\
:pb#196608:ob#0:bb#4096:fb#512:\
:pc#196608:oc#0:bc#4096:fc#512:
How can I tweak these numbers to get some more space on the ZIP disk? Is
is not safe? (I realise on hard disks Unix keeps some extra "invisible"
space aroud, but is it necessary on ZIP disks?) - also, is is possible to
format them with FAT16? mkdosfs complained when I tried.

Would you consider sharing your script?
