What does /etc/fstab show? Just upgraded? I'll bet it is #'ed out.

It _might_ be that with the new kernel your "hdb" has now become "sr0",
that is: is treated as a S-ATA device instead of IDE.

On some chipsets, especially the Intel ICH series, the hardware can
emulate BOTH ways, that is, can make IDE look like S-ATA or the
other way 'round. And then, when the kernel initializes S-ATA first,
all previous hd? devices suddenly become sd? cq sr?

Look in "dmesg" to see how the devices are recognized.

Hi guys:
First of all thanks you all for taking the time to help, it's very

I,m testing with an audio CD, i noticed the problem because when i
insert the cd kde does not pop up the window in which asks you what
you want to do with the media.

Mi cd it's still recognize as hdb acording to dmesg.

i'm thinking of making a fresh install but i prefer to find out what
went wrong because i also upgraded my desktop computer and did not
have any problem.

By the way, the machine with the problem it's a Lenovo 300 C100.

Your fstab line looks like this:

#/dev/cdrom  /mnt/cdrom   auto  noauto,users,ro  0   0

So the cdrom does not mount.

To see where it is attached, cd into /dev, and type this:

ls cdr* -l This command will list what the cdrom is actually linked to.
I'm betting that it will not be hda, but more likely hdb, which is your
second ide device. If the cdrom is not linked to hda, your first hard
drive, just edit /etc/fstab as root and remove the #, save fstab, and the
cdrom should work.

John.

Yep..
Your right.
Trying with data cd's and dvd's the thing goes fine. And I open KSCD
and played my audio cd ok.
But in 12.1 even the audio cd's were seen in the desktop and kde asked
me what i wanted to do with it.... In xfce it was showed in the
desktop too.
So what has changed since 12.1 so i can't see the audio cds in the
desktop or that kde does not ask me what to do with it?????
It's really a strange thing ;(.....

Any way.. Many thanks for your help to every one that took the time to
ask...
Cheers.

If it's really an audio CD, someone's already given you the answer.

You can't mount audio CDs (well, Lew Pitcher once mentioned an exception,
but most of us don't apply to that exception), it's not arranged as a data
filesystem. So it won't mount, though if it's in the drive and the drawer
is shut, starting up a CD player program likely will show something in
the drive (though it has to be made aware of which drive, which is the
purpose of using an alias like /dev/cdrom).

Try a data CD, and see what happens.

Hallo, jcamez,

Du meintest am 15.12.08:

That's no good idea - "dmesg" takes "/dev/hda" for the CD-ROM drive.

That can be a mess until one compiles a custom kernel or takes a whip to the
udev (?) setup scripts / whatever (I find putting in a custom kernel easier).

Yes, try:

$ dmesg |grep CD
hda: VMware Virtual IDE CDROM Drive, ATAPI CD/DVD-ROM drive
hda: ATAPI 1X CD-ROM drive, 32kB Cache
Uniform CD-ROM driver Revision: 3.20


In KDE a CD becomes /media/$cd_volume_label presumably due to the udev
plus friends magic. For example after 'inserting' the vmware tools CD
and allowing the KDE thingy to open the new file, I find that I have:

$ df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/root 8001052 5445416 2149192 72% /
tmpfs 452528 0 452528 0% /dev/shm
deltree:/home/common 8224960 2231744 5993216 28% /home/common
/dev/hda 196384 196384 0 100% /media/VMware Tools

users must have plugdev and disk in the user group give it permision.
slack12.2 hal is looking for your user permissions.
