laptop - cd/dvd rom not recognized (Kubuntu)

[garnertr]

Greetings,

Linux dweeb here and I'm afraid that I've either have a software glitch and/or hardware issue...

I want to ensure that my /etc/fstab is set up correctly for my dvd/cdr drive, and I'm not sure if it is...

tom@tardis:~$ cat /etc/fstab
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
/dev/hda1 / ext3 defaults,errors=remount-ro 0 1
/dev/hda5 none swap sw 0 0
/dev/hdc /media/cdrom0 udf,iso9660 user,noauto 0 0

I've done a sudo mount -a to force recognizing, but alas, it is not working. I want to ensure that my /dev/hdc -> /media/cdrom0 is 100% correct, but how do I do that?

Any ideas on how to ensure 100% that my settings are correct before I move on to hardware problem?

if it is a cd burner it will use scsi emulation change your /dev/hdc to /dev/sda, should work then. Good Luck!

As as fellow Washingtonian, welcome to the JL forums..stick around it's a hoot! BTW, why is it everyone I meet from up in your area are missing teeth, or is that just in Maltby? j/k! :p

What error did it throw? Does the directory /media/cdrom0 exist?

ok, I've made the change in my /etc/fstab to reflect /dev/sda vice /dev/hdc


tom@tardis:/media$ cat /etc/fstab
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
/dev/hda1 / ext3 defaults,errors=remount-ro 0 1
/dev/hda5 none swap sw 0 0
/dev/sda /media/cdrom0 udf,iso9660 user,noauto 0 0

tom@tardis:mount -a
tom@tardis:

OK, I popped open my drive reinserted a music cd (commercial, not a ripped and/or mp3 disc...)

same thing, nothing happens...

The drive whiles up like its trying and then shuts down... I have duty tomorrow and will bring my laptop to work, there is a person in my duty section that has the same brand of laptop (alienware - sentia) so I'm going to swap out drives, maybe mine is bad? I don't know now... but I just want to ensure that everything on the software side is 100% correct...

Thanks, I found this site via my search for my issue regarding my drive and I thought why not register, it seemed cozy... and btw I'm NOT fr WA, (worse, I'm fr TX), I'm just stationed in Everett and work here for military duties (ie, I'm Navy)...

Thanks for the tips..

What error did it throw? Does the directory /media/cdrom0 exist?

I get no errors, I can place an actual real purchased music cd in my drive, it spins up, like its starting and then spins down, I can see the dr light blinking on/off and then nothing...

Listed is my /etc/fstab file...

tom@tardis:/media$ cat /etc/fstab
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
/dev/hda1 / ext3 defaults,errors=remount-ro 0 1
/dev/hda5 none swap sw 0 0
/dev/sda /media/cdrom0 udf,iso9660 user,noauto 0 0

In my media folder are two directories - cdrom and cdrom0

thanks for your assistance, anything to help is most appreciated... thanks again...

when you pop in a cd and after it spools up can you dmesg and get any info that will tell you what drive is trying to work...I may have sent you off into the wild blue with the sda thing...my bad... :o. I don't think you should have had to change to /dev/sda to get it to work. It could be listed as /dev/hdc like yours was or /dev/cdrom /dev/cdrom0 . sudo mount -a /media/cdrom did not work...can you run sudo mount /media/cdrom0/ -o unhide and get any results?

PS- I take the Snohomish Co. bashing back. :p

If it's a 2.6 kernel, it will be /dev/hdc....2.4 kernels used scsi emulation, but that's old now.
And you DON'T mount audio cd's. Just point whatever audiocd playing software you have at /dev/hdc...

Also, you nee a comma between iso9660 and user, also perhaps add nosuid
