Hello,
I have an
hdc: HL-DT-ST DVDRAM GSA-4120B, ATAPI CD/DVD-ROM drive
from LG. My kernel is a vanilla 2.6.11 with packet writing enabled. I noticed,
however, that I can mount and write a CD-RW udf formatted with
# cdrwtool -d /dev/hdc -q
without the need of the pktcdvd driver (with the module unloaded, indeed),
simply with
# mount -t udf /dev/hdc /mnt
I thought that this was a property only of DVD+RW and DVDRAM media. Am I
missing something here? What is then the use of pktcdvd driver?
Thanks in advice,
Joao Luis M. Assirati.

Hi;
Well, I have only tested this with dvd+rw (and mount with the
noatime option, to avoid wearing out your media), and it is just *way*
to slow, vs. pktcdvd. I gave up on a copy that would have taken a minute
or two under pktcdvd after over an hour with just the block device
mount.
Of course, pktcdvd gives me and others pretty consistant data
corruption. (see bug 4290 on bugzilla.kernel.org)

ps. others have reported that mt. rainier support works well, and obviates
pktcdvd.
