How do I mount a CDrom or DVD writer?


When I do " mount /dev/cdwriter /mnt/cdwriter "

I get a message saying only root can do that, then when I do it as root I

get a message saying " no media found ", but I know there is somthing on

the disks I have been trying to mount.


What should I do?

did you create your mount point /mnt/cdwriter with mkdir ?

you can also use the command dmesg|more to see if linux was able to see your cdwriter on bootup

Now that you have created the mount point, try issue the following
Code:
mount -t iso9660 /dev/hdc /mnt/cdwriter

As user I get " only root can do that "
and as root I get no medium found.

yes only root can mount the cdrom unless you add your user to I think the wheel group or cdrom group. I just tested and your error will pop up for one of the following conditions.

1. No Cd is in the drive
2. Cd is blank
3. Mounting wrong removable media drive.

So I would start by checking that you don't have the cd in the wrong drive.

OK your right. I tried the other drive the (non writer) and it mounts

automatically in KDE and I dont have to do anything from command line.

Obviously the next question is..... How do I get the DVD/CD writer to do

that?

the exact same way that you just did for the cdrom. If it doesn't work than you might have something wrong with your hardware (cd writer).

Hmmm..... I think I will remvove the cdrom alltogether and hookup the writer where the cdrom was and see what that does.

Another odd thing is that the cdrom opens up in KDE as A writer, not as a cdrom, but the writer does not open up at all.

Does anyone have any idea why Linux cannot mount or see whats on a CD that I know has data on it?

It seems if Linux is supposed to be such an advanced OS then mounting should be A simple operation, instead of locking up, not seeing data on a disk or giving some strange messages from the command line.

Ive tried all the advice, googled for an hour on the subject, read the man pages for mount and fstab and nothing seems to work.

What else should I try to get Linux to recognize CDrom drives or the data on a CD?

Was this working before on some other type of software?

Does your bios see both drives?

Are they pata or sata drives?

If pata do you have the master/slave/cable select jumpers in the right spot?

If bios does not see the drive no OS in the world is going to see it either....
