The UDFtools package contains utilities for creating and mounting CD-RW disks with udf file systems for both reading and writing. UDF files systems are used on both CD-RW media and on DVD. For more details of the UDF file system standard see: http://www.osta.org and http://www.ecma-international.org.

Required Patch: http://www.linuxfromscratch.org/patches/blfs/5.0/linux-2.4.22-packet.patch
Patches for other kernel versions: http://w1.894.telia.com/~u89404340/patches/packet/
| Warning |
Note that this patch can permenantly damage your CD drive if it is from one of the few mentioned at http://slashdot.org/article.pl?sid=03/10/25/1737244. Do not apply the patch without first checking out the article. |
Install the kernel patch by running the following commands from the kernel source directory:
patch -Np1 -i ../linux-2.4.20-packet.patch |
In the kernel configuration, check your setting with those listed here:
Block devices
Packet writing on CD/DVD media: Y or M
File Systems
UDF filesystems support (read only): Y
UDF write support (DANGEROUS) Y |
If necessary, recompile the kernel with
make CC=/opt/gcc-2.95.3/bin/gcc dep && make CC=/opt/gcc-2.95.3/bin/gcc bzImage && make CC=/opt/gcc-2.95.3/bin/gcc modules && make CC=/opt/gcc-2.95.3/bin/gcc modules_install |
Copy /usr/src/linux/arch/i386/boot/bzImage and /usr/src/linux/System.map to /boot. If you utilize LILO edit /etc/lilo.conf appropriately and run lilo.
If you build packet writer as a module, add the following to /etc/modules.conf:
alias block-major-97 pktcdvd |
Finally, create the packet driver device nodes in /dev, add one node for every CD-RW drive you want to support:
mknod /dev/pktcdvd0 b 97 0 mknod /dev/pktcdvd1 b 97 1 |
Install UDFtools by running the following commands:
./configure --prefix=/usr && make && make install |
The UDFtools package contains pktsetup, cdrwtool, and mkudffs.
pktsetup is used to establish and break down associations between the kernel packet driver and a physical drive.
Example:
pktsetup /dev/pktcdvd0 /dev/scd0 mount /dev/pktcdvd0 /mnt/cdrom -t udf -o rw,noatime |
cdrwtool provides facilities to manage CD-RW drives, including formatting new disks, setting the read and write speeds etc..
Example:
cdrwtool -d /dev/scd0 -q |
mkudffs is used to create new UDF file systems, it can be used on hard disks and CD-R as well as CD-RW.
