Indeed, one would expect that a disk image utility would write the whole formatted image
on the disk and be done with it.
I had all sorts of problems writing disk images on the target platform that I thought were
communications related, which disappeared when I formatted the disks. Interestingly, CP/M
images seem to write just fine on DOS formatted disks so go figure.

This is a disk image tool so it doesn't matter what OS you use to
formatthe disk, just as long as the disk is formatted.
If indeed DSK2FILE requires the disk to be pre-formatted as you
say then
that's probably what was causing the troubles Zane was having.
Lame lame
lame. Some people shouldn't be allowed to write software.

It depends on how the image is being written. If it's being written from
a disk image that contains "raw" disk bytes then you could simply write
the image to disk and that's that. However, if the image is comprised of
tracks and sectors, the disk must be formatted in order for the image to
be written, just as you would need the disk to be formatted to store and
retrieve files.
In this specific case, the software should've either told you it needed
the disk you were writing to be pre-formatted (I would assume it mentions
it in the docs) or it should give you the option to format the disk before
writing. In the very least, it should've made it obvious to Zane that it
was having trouble writing the disk. Apparently it didn't, and that's
just crap programming.

In all fairness to the author, it might say something about this in the
documentation. However, the software is so easy to use that I never looked
at it.
At the same time, give the nature of the program, and the fact it should
take an almost exact amount of time to write a disk image, giving that
amount of time would have been a good hint.
OTOH, the fact that even knowing I need to format the disk first I can't get
a working floppy created is enough to drive me crazy. I should have been
smart and tried a different program to write the disk images...
