Trouble mounting DVD/CDRW


Hello, I'm a noob using Slackware 10.2 on my Compaq Evo n600c, a laptop, and I'm having trouble mounting my DVD/CDRW. I have browsed the man mount info, and when I enter
mount -t iso9660 /dev/hdc /mnt/cdrom

I get the wrong fs type, bad option, bad superblock error.

My fstab looks like this for the cdrom,

/dev/hdc /mnt/cdrom iso9660 noauto,owner,ro 0 0

Now it looked like this, which I commented out,


/dev/cdrom /mnt/cdrom iso9660 noauto,owner,ro 0 0


I don't know what to do. I had ATAPI-SCSI enabled in lilo.conf, but got rid of it and the problem still exists. There is no network currently available to the laptop with Slack on it, so If I can't get this friggin cdrom mounted I'm screwed. I'm sure I'm doing something foolish, can anyone help?

firstly, i guess /dev/hdc is your cdrom device.
Have you checked that ? (if not run "dmesg|less" and see what is says)

Does the disc you are trying to mount contain a iso9660 filesystem ?
The kernel tries to automatically detect the filesystem, so try a simple
"mount /dev/hdc /mnt/cdrom" and see if it gets mounted.
also try "cat /proc/filesystems" to see what filesystems your system supports (all those not starting with "nodev")

as last thing, you are trying to mount a data cd right ? (not an audio cd)

Alright heres an update. I got the thing working, by adding the hdc=ide-scsi line to the lilo. And then in the fstab I changed the hdc to sr0 and it works now.

But I still get that read only. How can I make it so that I can burn cds with the cdrw?

Secondly, how should I go about so that the device will mount ever time my main user logs on?

linux does not have drag and drop CD writing capability like windows and you can not mount a blank CD. The CD writing application accesses the device directly and does not use /etc/fstab.

10.2 cdrom/dvd mnount

With 2.4.31 kernel u need the hdc=ide-scsi append line in lilo then hdc becomes sr0 or scd0. Your fstab line has 'owner' wc means only root can access it. Change 'owner' to 'user'.
And as root at cli do pico /etc/group and add ur username to cdrom,disk,audio,games,video and sys groups ctl-x then y to save changes.
Audio or music cd are not mounted. kscd can play cd. xine can play dvds. K3b or other such program can be used for recording.
If u have 2.6x kernel then the append line is not used.
Review SBINGS SLW10.2 FAQ and 'this is how i do everything' at top of slackware forum.
Also search for others with ur laptop who have slw installed in forum. Happy slacking.
