A few questions:
Does /dev/[r]sd0* exist? Maybe check that.
Try running
fdisk sd0
to see how the disk is partitioned. Here's what a virgin Zip disk has
for its partitioning:
******* Working on device /dev/rsd0 *******
parameters extracted from in-core disklabel are:
cylinders=96 heads=64 sectors/track=32 (2048 blks/cyl)
parameters to be used for BIOS calculations are:
cylinders=96 heads=64 sectors/track=32 (2048 blks/cyl)
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 0 is:
<UNUSED>
The data for partition 1 is:
<UNUSED>
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
sysid 6,(Primary 'big' DOS (> 32MB))
start 32, size 196576 (95 Meg), flag 80
beg: cyl 0/ sector 1/ head 1;
end: cyl 95/ sector 32/ head 63
I can mount the DOS partition with
mount -t msdos /dev/sd0s4 /mnt
If you want to put UFS file system on a Zip disk, you'll have to
change the partition table using `fdisk -u sd0'. I generally dedicate
a full Zip disk to UFS and put it on partition 0, so I can use
/dev/sd0[a-h]:
localhost# fdisk -u sd0

We haven't changed the partition table yet. This is your last chance.

Next, you'll want to write a disklabel. I haven't done that in a
while and lost my canned disklabel in my 2.1.5->2.1.6 upgrade, but you
can probably find one in the FreeBSD mailing list archives.
