Sorry, it was a typo. It should be UDF.
Did you type "mount -t udf /dev/sda1 /mnt/somewhere"? That won't work
for any CD-RW, because A) CD-RWs are not seen as disks, but CD-R*
devices B) CD-RWs aren't partitioned. You probably want:
mount /dev/scd0 /mnt/somewhere

...just like a normal CD-R*. Insert "-t udf" if necessary, but
I did a 'mount -t udf /dev/sr0 /mnt/usbdrive and when I have a blank
DVD+R disk in the USB DVD drive, this is what I get:
root@xxxxxxxxxxxxx:/usr/bin# !moun
mount -t udf /dev/sr0 /mnt/usbdrive
end_request: I/O error, dev sr0, sector 64

You can't mount a blank DVD+-/CD; there's no filesystem on it. You have
to mkudffs on it first. However, you shouldn't mount a UDF DVD/CD and
expect to write to it until you know for sure that you have UDF write
support enabled. You didn't respond to that part of my message and
your kernel's old, so I would guess that you don't have that. Use
growisofs with the -udf option to write to DVD+Rs if you want UDF DVDs.
Or use k3b; it's really a very nice frontend.

Then I used my Windows XP to burn some files on the blank DVD+R disk
and when I tried to mount it again using the same command as before,
UDF-fs: No VRS found

Your 'Doze program almost certainly wrote things in iso9660, then. You
should only use -t with mount if just plain mount doesn't work.
