CD/DVD Drive Problems After 9.1 -> 10.0 Mandrake Upgrade

I'm having a lot of problems after the upgrade, but one is really vexing; the CD/DVD drive seems to mount, but seems not to, also. If I put in a music CD, KDE will play it. But if I insert a data CD, nothing. If I try to ls /mnt/cdrom, nothing happens, nor will Konqueror display anything.

Here's what mount looks like:

/dev/ide/host0/bus0/target0/lun0/part2 on /type ext3 (rw,noatime)
none on /proc type proc (rw)
none on /proc/bus/usb type usbdevfs (rw)
none on /dev/ type devfs (rw)
none on /dev/pts type devpts (rw,mode=0620)
none on /mnt/floppy2 type supermount (rw,nosuid,nodev,dev/dev/fd0,fs=ext2:vfat,--,codepage=850,iocharset=iso8859-1,umask=0,unhide)

cat /etc/fstab prints out:

/dev/hda2 / ext3 noatime 1 1
none /dev/pts devpts mode=0620 0 0
/dev/hdc /mnt/cdrom auto umask=0, user, codepage=850, iocharset=iso8859-1,noauto,ro,exec 0 0
none /mnt/floppy2 supermount dev=/dev/fd0, fs=ext2:vfat,--,codepage=850,iocharset=iso8859-1,nosuid,umask=0,unhide,nodev 0 0
none /proc proc defaults 0 0
/dev/hda1 swap swap defaults 0 0

The laptop's stats are:

PowerPro IV:28 ULTRA
15" SXGA+ TFT Active Matrix w/ATI Mobility Radeon 9000 w/64MB DDR,
2.66GHz IntelŪ PentiumŪ 4 Processor (Northwood) w/512k L2 Cache - 533MHz System Bus Speed,
60GB Ultra ATA/100 Hard Drive at 5,400 RPM,
1,024MB (2 SODIMMS) PC2700 DDR Memory,
Combo 8X DVD/24x10x24 CD-RW w/Softwares,
Built-in 56k V.90 Data/Fax Modem,
Built-in 10/100BaseT Ethernet w/RJ-45 Jack,
Built-in 802.11b Wireless LAN,
Smart Li-ion Battery

The hostname is sibilla.

If anyone can drop a few clues in my bag, I'd appreciate it.

Welcome to LQ! I think the only issue is that you simply need to mount the data CD before you can access it. For example (and running as root)
mount /dev/cdrom /mnt/cdrom
Give that a shot, and post back the results -- J.W.

Wow, that was quick!

Thanks, J.W. I'll do that, and post tomorrow. There's a problem with magicdev not being in there, which I think is causing part of the problem. All kinds of awful things happened ...

Have a great weekend,

There is a GUI setup for the hotplug system. It may be set to work with Music CD's but not data CD's. Also, your configuration for mounting the CD may be a hold over from the 9.1 setup. Another possibility is that the fstab entry was changed by another setup program, such as the k3b setup.

If you insert a data cd and wait a few seconds, how does the output of the mount command look then? From looking at the /etc/fstab, you need to manually mount the /mnt/cdrom device after inserting a cdrom.

I'm not near my linux box now, and I recently changed to SuSE 9.1 Pro, so someone else will need to give you particulars on the hotplug scripts in /etc/sysconfig. ( Impulse purchase when shopping at Best Buy! )

The 'Mount points' MCC section may provide an easy way to make the changes you want to make, by simply checking the automount box. I think you have the cdrom drive in the hotplug scripts, but the fstab entry isn't using the automounter. I believe that the cdrom's fstab entry should look more like a floppy or usb drive entry, however, I pulled the hard drive that had mandrake on it out of my computer so I can't check to make sure.
( If Promise would put out a raid driver for 2.6 kernels, I'd cut the XP partition in half and re-install Mandrake 10 on my raid drive )

I hope this helps. Good Luck!

Hey folks,

su'ing and mount /dev/cdrom /mnt/drom turned the trick, and I think the files may be configured for the 9.1 setup. I believe I'm gonna slurp some things off her that I really need, and go with a fresh install ... the mess is pretty amazing.

Thanks again,
