I just read that you wanted me to change the fstab stuff, and i tried and it won't let me delete or add anything...

You need to be root in order to change fstab.
type "su" to become root.

By the way, you should post complete error messages. Simply saying it does not work will not allow us to help you to the best of our ability!

you don't necessarily need to change the fstab. that was just a suggestion.

here's the root of the problem
/dev/cdrom/ is not a directory, it contains nothing: no files, no data.
/dev/cdrom is a driver. all the files in the cdrom are located in its mountpoint

looks like a lesson in the unix mount system is in store....
some background on the fstab: "file system table"
All devices in the unix system exist as files that are located in a directory called /dev. In order to build the unix file system, we need to make mount points, or places where we attach the device "drivers" to the unix file tree. You can specify any device to any mountpoint that you want (except for the root file harddrive, that must be located at mountpoint /) The /etc/fstab configuration file is actually relatively simple:

one of your fstab lines looked like this:

Code:

/dev/hdc /media/cdrecorder auto pamconsole,exec,noauto,managed 0 0

the first entry, on a line /dev/hdc is the device file that you want to mount. the second field on this line, /media/cdrecorder is the mountpoint. In order for the device to be mounted, the mount point MUST EXIST. the third field, yours is labeled "auto" is the file-system type. auto is ok, but I would suggest labeling this iso9660, which directly specifies it as a jolliet filesystem (cdrom iso). the fourth field, "pamconsole,exec,noauto,managed" are your user flags. This field tells which users or groups can mount/unmount the device. This section also contains the read-only or read/write flags for the device. The final two fields "0 0" represent the dump command and reboot checkup respectively. DON'T SCREW AROUND WITH THOSE. So, what we've learned by this little history lesson is that the fstab has shown you that your cdrom device /dev/hdc is being mounted at the mountpoint /media/cdrecorder. All files on the cdrom can be found in this directory when the device is mounted

So basicly it I need to change the auto thing in my fstab. And also when I tried changing the Fstab in root it still did not let me, it just opened it in a text editor but wouldn't let me acually change things. Sorry for being new to linux and posting, and thanks for the help. So after I change the fstab I should be about to mount if I put mount /dev/hdc /media/cdrecorder ? Sorry I would try it now but I am on a windows machine at school. so is that what you guys want me to do?

***Forget I ever said to change your fstab. just

Code:

$ mount /dev/hdc
$ cd /media/cdrecorder
$ ls ./

(the $ is not to be typed into your command prompt, I just put it there to represent that you are doing this as a normal non-root user)
the files for your cdrom drive should be there. if not, then we have some other problem. Don't be sorry for being new to linux, we've all been there and done that... but once you start to learn the basics, it's one hell of an operating system!

SIDE NOTE
i'm guessing the reason why you can't manually change the fstab is b/c FC4 (I've never used it, so it's a guess) uses an external program to "dump" data into the fstab.

Code:

# This file is edited by fstab-sync - see 'man fstab-sync' for details

that's why I say that.

I just realized why you might be thinking that you can't edit your fstab. This is a wild guess, but:

you are using the

Code:

vi /etc/fstab

command, and in order to type anything into the vi editor, you have to type the letter "i" for insert. that lets you type into the vi editor. then, in order to save, you need to press esc and type in ":wq" for write and quit.

ALSO, for anyone inquiring into this thread, I think the best way to determine what the root file for your device is would be by running:

Code:

bash$ df

I just realized that... but it would require the device to be mounted, so i guess it sorta doesn't work for this thread haha
