Ok, to continue the saga and change the question, I found the 
following:

http://www.linuxquestions.org/questions/linux-hardware-18/how-can-i-format-a-dvd-ram-501752/

where it is suggested to simply format (and partition, I have assumed) 
the disk in ext2 using the standard tools.

So I did. fdisk for one partition of type 83, then

mke2fs -b 2048 /dev/hdc

which seemed to work just fine.

However, when I put the disk in, the following again came up:

[14455.902724] UDF-fs: No VRS found
[14455.902732] UDF-fs: No partition found (1)
[14455.997756] ISOFS: Unable to identify CD-ROM format.
[14456.246923] UDF-fs: No VRS found
[14456.246930] UDF-fs: No partition found (1)
[14456.341842] ISOFS: Unable to identify CD-ROM format.

Looking in /etc/fstab, I see:

/dev/hdc        /media/cdrom0   udf,iso9660 user,noauto     0       0

which may very well be why there are UDF errors and why ext2 won't 
mount. Let's try putting "auto" in there...

/dev/hdc        /media/cdrom0   auto    user,noauto     0       0

And it worked.

# df
Filesystem           1K-blocks      Used Available Use% Mounted on
...
/dev/hdc               4402628     11284   4167674   1% /media/cdrom0

Adding a file, deleting, both worked just fine treating it as a 
regular disk.

My apologies for bothering the list with something already pretty well 
answered, but my searches had not turned up the information I needed 
when I did the searches the first two times.

I'll also try UDF to see if it's readable on Winders, since who knows 
wtf I'll be needing to mount backups on in several years. I've lost 
too many pictures that were stored on floppies already.

Thank you for your time,

Curt-
