Ubuntu

dvd drive device name

Asked by Alpo Turunen

Before upgrading to Hardy my IDE CD/DVD burner was on /dev/hda and there were symlinks
/dev/cdrom -> /dev/hda
/dev/cdrw -> /dev/hda
/dev/dvd -> /dev/hda
After upgrading the drive has changed to /dev/scd0. That is not the problem but now the symlinks are
/dev/cdrom2 -> /dev/scd0
/dev/cdrw2 -> /dev/scd0
/dev/dvd2 -> /dev/scd0
And there are no /dev/cdrom, /dev/cdrw or /dev/dvd.
How can I change the names of the symlinks back so that programs trying to read /dev/cdrom will work normally?

Try the following :

# cd /dev
# sudo ln -s /dev/scd0 ./cdrom
# sudo ln -s /dev/scd0 ./cdrw
# sudo ln -s /dev/scd0 ./dvd

simply making new symbolic links

That doesn't work because /dev is on tmpfs and is regenerated by udev on every boot, so the symlinks will be lost. Is there a way to change symlink names in config files?

Take a look in /etc/udev/rules.d/70-persistent-cd.rules and /etc/udev/75-cd-aliases-generator.rules
