udf patch and samsung cdrw/dvd sm-352f (dell gx280) not compatible

Hello,
I have a dell at work and I would like to write packet writing cdrw with it.
But it appears that it has a drive not compatible with your patch.
This is my software and harware specifications:

samsung cdrw/dvd sm-352f, firmware T902
/dev/pktcdvd/0=>/dev/hda
kernel 2.6.13
udftools deb package v 1.0.0b3-10
dell GX280
----------------------------------------------------------------
When I format the cdrw:

# cdrwtool -t12 -q -d /dev/hda
setting speed to 12
using device /dev/hda
1914KB internal buffer
setting write speed to 12x
Settings for /dev/hda:
        Fixed packets, size 32
        Mode-2 disc

I'm going to do a quick setup of /dev/hda. The disc is going to be 
blanked and formatted with one big track. All data on the devicewill be 
lost!! Press CTRL-C to cancel now.
ENTER to continue.

Disc capacity is 295264 blocks (590528KB/576MB)

Do you know what the matter with this drive?
