Did it ever work on the same hardware that gives you problems now? If so,
what kernel/udftools versions did you use?

Strange, 02.04.04 means "LOGICAL UNIT NOT READY, FORMAT IN PROGRESS". Does
this patch for udftools-1.0.0b3 make any difference?

You can't run mkudffs directly on /dev/hdc, because it's not possible to
write random 2kb blocks to /dev/hdc. You have to use /dev/pktcdvd instead:

# pktsetup /dev/pktcdvd0 /dev/hdc
# mkudffs /dev/pktcdvd0
