Nopers. The create worked, but the same problem when I tried to copy the
mkudffs dir over:
cp -a mkudffs /mnt/cdrom
cp: cannot create directory `/mnt/cdrom/mkudffs': Input/output error

      

you have of course mounted it as rw?

    

dmesg:
UDF-fs INFO UDF 0.9.6-rw (2002/03/11) Mounting volume 'LinuxUDF', 
timestamp
2002/07/17 19:27 (1ed4)
 I/O error: dev 0b:00, sector 1096

      

i have a similar problem, though i am actually able to write what seems 
to be a random number of MBs for each time i mount the drive.

--
i the try to copy a 500MB file onto the disk:

# cp -i cd3.iso /mnt/dvd+rw/
cp: /mnt/dvd+rw/cd3.iso: No space left on device
#

my dmesg at this point is:
 I/O error: dev 0b:00, sector 1108
 I/O error: dev 0b:00, sector 1108

the size of the file written to the disk is ~99MB.

if i now unmount the drive and remount it, i can write some additional 
bytes to it. For each time i do this, the lost+found directory appears 
and disappears on an apparently random basis.
    

Out of curiosity, is the background format complete when you try and mount
the disc, or is it ongoing? (maybe every time you mount/umount the disc, more
of it has been formated so you can use more...)

If you say, dd if=/dev/zero of=/dev/sr0 bs=2048 count=(however many blocks on the dvd+rw),

then run mkudffs and mount it, can you write the whole file right away?
