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:

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.



my dmesg at mount:

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.



:(
