Can't mount cd-rom in Fedora Core 2


I can't mount my cd-rom in Fedora Core 2. (using gnome)

fstab entry:

Code:
/dev/cdrom    /mnt/cdrom    udf,iso9660    noauto, owner, kuzdu,user,rw    0 0
startup gives the following error message, same as with manual mounting (# mount /mnt/cdrom/):

Code:
mount: block device /dev/cdrom is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
       or too many mounted file systems
I've also tried with substituting "udf,iso9600" with auto (which works fine in SuSE)
What am I doing wrong?

to solve this problem, i had to run the test and then between all the options give 5 minutes. also i font suggest fedora because i am using it and it is just the bare os and no good commands are included such as pine and pico.

cdrom problem

instead of trying to mount /dev/cdrom try using the proper device label like /dev/hdc. maybe there is a problem with your symbolic link.
*just a suggestion*

I would understand the problem with the link if I didn't see the same error during startup... something is definitely not correctly configured, but what?

Here is my default entry created during installation .. and wonder why you change the 'ro' bit to 'rw' .. (ro means read only, while rw means read/write) ..

/dev/cdrom /mnt/cdrom udf,iso9660 user,unhide,noauto,owner,kudzu,ro 0 0

um... are you running the stock fedora core 2 kernel or have you custom-built your own vanilla kernel? If you're running the stock fc2 kernel then disregard this post. but if you're running the vanilla kernel, maybe you didn't compile support for the iso9660 and udf filesystems, or IDE drivers for the cdrom.

No, you do not need the rw even if you've cd-rw since you'll not able to mount your cd-rw in rw mode anyhow..

No custom kernel (still need to learn how to )

If I can't mount my cd-rw as rw can I still use rw disks? Is there a drag-and-drop utility to put files on a cd-rw?

Changed fstab to your entry and everything is working fine! Still alittle puzzled why it wouldn't work before and what some of the parametres mean. My guess was that "noauto" would not automatically mount the cd but when I insert it mounts (fine with me though). Kudzu...?? Anyway, it's fun seeing how I can solve my problems with you guys helping out a bit. Thanx

Here is a great site (little outdated) in regards to what all the lines mean in fstab.

ro is read only. You cant write to a cd-rom or cdrw anyway. This doesnt mean burning a disk it just means writing to the filesystem. Put in a music cd, open the contents of the drive. You will see the track list. Grab any file and try to copy it there, cant. Because you cant write to it without actually burning to the CD which is another thing all together. That is why ro is used when mounting cd-roms. Because they arent writeable filesystems.

http://www.tuxfiles.org/linuxhelp/fstab.html

I have been looking into modifying my own fstab to allow automounting of my NTFS drives and this has helped...

Thanks for the resource. I really appreciate it. Still, I'm not completely happy with your explanation about ro permissions for cd-rom. I admit that doing rw under windows requires a program to be running in the background, but it is possible to use a cd-rw like a hard drive (only slower) dargging and dropping files to and fro. I suppose no such utility is available in Linux (yet) but it could exist

Just FYI, but pico has been replaces with nano, which offers a few more features regarding a notepad-style text editing mode.

Now that I know about pine being removed though, I am thoroughly disappointed.

Fedora Core's mounting system is quite problematic, and certainly deserves a thread.

I had similar problems mounting a cdrom, we were using autofs and , most significantly were using /etc/auto.mnt, which was locking up the /mnt/ dir for anything other than autofs mounts. Renamed /mnt/cdrom in the fstab for /cdrom and all was well again..
