Glad it helped - muddling through does work sometimes!  I don't think
cdrecord would create the device - FreeBSD 5.x seems to create them
automatically in the right circumstances.

If you look at your Zip disk with fdisk (fdisk /dev/da0), you will see
the four partitions.  I had some where #4 was the partition with the
data.

Here is the result on a USB flash drive: it shows that partition 1 has
the data, and I must address it as /dev/da0s1

501 ~ # fdisk /dev/da0
******* Working on device /dev/da0 *******
parameters extracted from in-core disklabel are:
cylinders=62 heads=64 sectors/track=32 (2048 blks/cyl)

parameters to be used for BIOS calculations are:
cylinders=62 heads=64 sectors/track=32 (2048 blks/cyl)

Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
sysid 6 (0x06),(Primary 'big' DOS (>= 32MB))
    start 32, size 127712 (62 Meg), flag 80 (active)
        beg: cyl 0/ head 1/ sector 1;
        end: cyl 498/ head 7/ sector 32
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
<UNUSED>


I can't experiment any more, because my IDE Zip drive died, and it is
not worth replacing since CD burners reached a reasonable price.
