can't find cdrom on 13.1
 

music players can't find the cd player on slackware 13.1.
system still works with 13.0. With 13.1 I can boot off the CD.

tried mounting a data cd with (as root) mount -t iso9660 /dev/sr0 /mnt/cdrom and replacing sr0 with anything I could think of but kept getting message that the device did not exist.

Try ls /dev that should give you available devices.

tried ls /dev and tried to mount with anything that looked remotely promising with no success - think it is supposed to be sr0 - I did an upgrade from 13.0 maybe I neglected to change something (there was a list of things to change manually some of which I did and some I let slide).

Hi,

Do you have the user in the proper groups?
:hattip:

groups are OK - good thought tho - must have left that alone when I upgraded to 13.1

Hi,

What do you see with 'ls -al /dev/cdrom'?
:hattip:

bash-4.1$ su

bash-4.1# ls -al /dev/cdrom
ls: cannot access /dev/cdrom: No such file or directory
bash-4.1#

Hi,

Try 'su -'.
Or
'/bin/ls -al /dev/cdrom'.
:hattip:

bash-4.1$ su -

root@cellar:~# /bin/ls -al /dev/cdrom
/bin/ls: cannot access /dev/cdrom: No such file or directory
root@cellar:~#

when all else fails read the instructions.

from the slackware notes on upgrading I found:

You will almost surely want to remove the udev rules file for cdrom
devices (it will be regenerated on the next boot with correct
information reflecting the new libata stuff):
# rm -f /etc/udev/rules.d/70-persistent-cd.rules

I did that then rebooted but the 70-persistent-cd.rules didn't get regenerated.

so I tried:

bash-4.1# /lib/udev/write_cd_rules
Missing $DEVPATH.

don't know what the dollar sign means or how to fix the DEVPATH error

do these lines from dmesg have anything to do with this?

Hi,

Over looked the 'upgrade' portion.

How did you upgrade? You should follow 'UPGRADE.TXT' & 'CHANGES_AND_HINTS.TXT'.
:hattip:

Hi,

Looks like libata_switchover HOWTO will be of use here. 'libata_switchover' has been around since 13.0 but some new users are not aware. A new user should look at rworkman's 'libata_switchover HOWTO' to understand and be aware of the changes when using Slackware 13.0 & Slackware 13.1. Especially when performing upgrades or introduction to Slackware 13/13.1.

How do you have things configured?

Moved to the main Slackware forum as it's not an installation question.

yes I did read all that stuff. plot thickens as had upgraded all three of my computers to 13.1. on a second one had no trouble accessing sr0 (cd player) the player workbone went right to work.could also mount and read a data CD.

the /etc/udev/rules.d/70-persistent-cd.rules had been updated on that machine - don't think I did that manually.

refreshing to have a project as everything works/installs so good these day have to search real hard for something to fiddle with.

if no solution appears will wait till slackware 13.2 and do a clean install.
