I bought an XBox 360 HD-DVD drive last week, not to use with an XBox, I don't own one, instead I intend to use it with my PC in Linux. I had hoped that when I plugged the drive in that Ubuntu would automatically detect it and mount the HD-DVD. Unfortunately this didn't happen. I was able to read CDs and DVDs but not HD-DVDs. Ubuntu detected the drive but couldn't mount the volume. This is because the Linux kernel included in Ubuntu doesn't support UDF 2.5.

This can be fixed by downloading a patched udf.ko kernel module and placing it in the /lib/modules/2.6.2x-xxx/kernel/fs/udf/ directory. This will only work if you are using one of the kernels listed below. If you use a 64 bit kernel then you should follow the instructions in 1b. You can find out what kernel you have by typing uname -r at a terminal.

• 2.6.24.19-generic
• 2.6.22.11-generic
• 2.6.22.12-generic
• 2.6.22.13-generic
• 2.6.22.14-generic

1a. Copy and paste the lines below into a terminal:

wget http://www.strapp.co.uk/files/udf-$( uname -r ).ko
sudo mv udf-$( uname -r ).ko /lib/modules/$( uname -r )/kernel/fs/udf/udf.ko

1b. If you aren't using one of the above kernels then follow the instructions below to build a kernel module for your machine.

sudo apt-get install linux-source
cd ~/
cp /usr/src/linux-source-2.6.24.tar.bz2 .
tar -xf linux-source-2.6.24.tar.bz2
cd linux-source-2.6.24

wget http://www.strapp.co.uk/files/UDF_2.50-linux-2.6.24.patch

patch -p1 < UDF_2.50-linux-2.6.24.patch

make menuconfig
make

sudo cp fs/udf/udf.ko /lib/modules/$( uname -r )/kernel/fs/udf/

2. Restart. Lets see if its all worked... If you have a HD-DVD in the drive then entering the below command should result in something like this:

dmesg | grep UDF

[ 471.844000] UDF-fs: Partition marked readonly; forcing readonly mount
[ 472.384000] UDF-fs INFO UDF 0.9.9.1 (2007/01/03) Mounting volume 'HDDVD', timestamp 2007/04/12 05:46 (103c)

3. Navigate to the HD-DVD mount point as root (You MUST be root else all you will see are 4 restricted "files" that are actually folders) and you should hear the drive spin up and away you go:

sudo su
cd /media/hddvd
ls -l

total 8
dr--r--r-- 2 4294967295 4294967295 1032 2007-04-12 05:46 AACS
dr--r--r-- 2 4294967295 4294967295 972 2007-04-12 05:46 AACS_BAK
dr--r--r-- 2 4294967295 4294967295 1056 2007-04-12 05:46 ADV_OBJ
dr--r--r-- 2 4294967295 4294967295 1932 2007-04-12 05:46 HVDVD_TS

If the HD-DVD still failes to mount:

1. Manually create a mount point:

sudo mkdir /media/hddvd

2. Find the device id of your your drive:

dmesg | grep scsi

3. In my case the XBox drive (TOSHIBA DVD/HD) was /dev/sr0. Now edit your /etc/fstab file to include the line below: (Substituting /dev/sr0 for your device)

/dev/sr0 /media/hddvd udf user,noauto 0 0

The latest of seba_manciulea's udf patches can be found at this Sourceforge page. Hopefully they will soon be included in the Ubuntu kernel and there will be no need to patch.
