%general-entities; ]> $LastChangedBy: $ $Date: $ 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: and . Download (HTTP): Download (FTP): Download size: &udftools-size; Estimated Disk space required: &udftools-buildsize; Estimated build time: &udftools-time; Required Patch: Patches for other kernel versions: Note that this patch can permanently damage your CD drive if it is from one of the few mentioned at . 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-&linux-kernel-version;-packet-1.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 built 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 associates the physical device /dev/scd0 with the kernel packet driver /dev/pktcdvd0, then mounts a UDF formatted CD-RW for read/write access. 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 prepares a new CD-RW for use and formats it with a UDF file system. mkudffs is used to create new UDF file systems. It can be used on hard disks and CD-R as well as CD-RW.
