Can't detect my CD/DVD's anymore

I've checked /etc/fstab and everthing seems ok :
#
# /etc/fstab: static file system information
#
# <file system>        <dir>         <type>    <options>          <dump> <pass>
devpts                 /dev/pts      devpts    defaults            0      0
shm                    /dev/shm      tmpfs     nodev,nosuid        0      0

/dev/cdrom             /media/cd   auto    rw,user,auto,unhide   0      0
/dev/dvd               /media/dvd  auto    rw,user,auto,unhide   0      0
#/dev/fd0               /media/fl   auto    user,auto             0      0

UUID=0b20f081-24f2-45a4-9358-74c91e352d4d / ext4 defaults 0 1
UUID=afcb1fcb-dbda-4005-92f6-24e8934ef971 /home ext4 defaults 0 1
UUID=cfa64325-4dbe-4fda-94c4-5f78204f391b swap swap defaults 0 0
UUID=f35ba78c-e28b-4c3b-863f-f798f33d0ed4 /boot ext2 defaults 0 1

on Thunar it doesn't pop up and on Rox I get this error :

"mount: block device /dev/sr0 is write-protected, mounting read-only
mount: I could not determine the filesystem type, and none was specified
Mount failed"

Is it an audio CD or maybe it's a blank (empty) CD?

> mount: block device /dev/sr0 is write-protected, mounting read-only
This part is 100% normal and true.

It's not a black CD it's an audio CD.

Re: Can't detect my CD/DVD's anymore

Audio CDs don't have any filesystem on them, they're just a stream of bits.
You can't copy the music "files" from the CD because there are none - you have to rip the stream (or parts of it) and create the needed files.

In other words, the output you get is OK, you shouldn't mount the audio CDs, just insert the CD and let the app you're using for ripping or playback handle it.

Re: Can't detect my CD/DVD's anymore

On a related note, you should delete these lines on /etc/fstab:

/dev/cdrom             /media/cd   auto    rw,user,auto,unhide   0      0
/dev/dvd               /media/dvd  auto    rw,user,auto,unhide   0      0
#/dev/fd0               /media/fl   auto    user,auto             0      0

Thanks ^_^v it works on VLC (exaile is complaining there is no URI handler for "cdda') but w/e.

Alrght, I'll delete them but can I know why?

Re: Can't detect my CD/DVD's anymore

There is no device called /dev/cdrom or /dev/dvd. Your CD drive is /dev/sr0 - so it's managed by HAL/DBUS and unneeded from /etc/fstab. ;-)

But they are symlinked, so there _is_ a file /dev/cdrom.

@ Jack450
Comment them out like you have /dev/fd0 (put '#' on the beginning of the line):

#/dev/cdrom             /media/cd   auto    rw,user,auto,unhide   0      0
#/dev/dvd               /media/dvd  auto    rw,user,auto,unhide   0      0
#/dev/fd0               /media/fl   auto    user,auto             0      0
