Mounting DVD to a CDR/DVD combo drive

buaku · 04-26-2005, 08:23 PM

Wonder if it'd be worth asking someone w/ either of those distro's for their fstab entries.

Or if you're bored reinstall a distro where it did work and try and find out where the settings would be.

Do you have udf support compiled into your kernel? If not add it. To check for it look in /lib/modules/current_kernel/kernel/fs/udf.

I use the following in my /etc/fstab

Code:

/dev/cdrom              /mnt/cdrom              auto    noauto,owner,rw 0 0

Then in my /etc/filesystems , I have udf in the list.

Only other thought is the dvd a press dvd or a burned dvd. Does the dvd support that type of media?

lib/modules/2.4.29/kernel/fs/udf$ ls
udf.o.gz

that is what is in that folder for the first one ... i think that means i have support..

However i do not have a file or folder named "filesystems" (nor anything similar) in /etc/

Maybe this could be the problem... As for dvd support goes three days ago (back in my Mandrake days) I read off the very same dvd for a paper.

Here is a copy of my /etc/filesystems file

Code:

ext3
ext2
rieserfs
xfs
nodev proc
nodev devpts
iso9660
udf
ufs
vfat
hfs

do you think if i just created one that it would work?... im gonna try it and restart

*Update*

:-/ didnt work....

i simply went to /etc/
pico filesystems
copied what you had
restarted

(Wasnt expecting it to work but at this point I'm willing to try anything)

As for what Buaku said :

Does anyone else with Slackware 10.1 and possible a Dvd Cd-RW combo drive have a fstab code they would like to share with me.. Thank you

You've a 2.4 kernel, so you should've added hdb=ide-scsi. Also when you do that the symlink is changed to a scsi one (I don' remmber if it was srX or sgX).
However this only affects (AFAIK) cd-burning, not reading.

I'm runnin 10.0 and I have a combo drive, it just doesn't burn dvds though.

my fstab line looks like...
/dev/cdrom /mnt/cdrom iso9660 noauto,owner,ro,user 0 0
Also running a 2.4 kernel.

I was able to mount a burned +r data disc and a commercially pressed movie disc.

What kind of dvd are you trying to mount? And what is the model of your drive? Have you tried looking around to see if any others have had problems with your drive?

f34r7h1s · 04-26-2005, 11:08 PM

yeah i have that now for my fstab and it doesnt work... Im trying to mount a data dvd + and i have no idea what the model is (its one from my gateway m500 laptop)

keefaz · 04-27-2005, 01:03 AM

It is possible that the problem comes with the dvd because you have tested all the
possible options in fstab, but anyway to make sure :

When you attempt to mount the dvd with mount /mnt/cdrom, what is the output with :
cat /proc/filesystems | grep -i iso

If you have no output, try as root : /sbin/modprobe isofs
then try : mount /mnt/cdrom

f34r7h1s · 04-27-2005, 07:42 AM

Ok think we are on to something... When I grep /proc/filesystems All that returns is iso9660

(im assuming i should have udf in there?)
so here is what my filesystems file looks like

Code:

nodev   rootfs
nodev   bdev
nodev   proc
nodev   sockfs
nodev   tmpfs
nodev   shm
nodev    pipefs
            ext3
            ext2
nodev   ramfs
             umsdos
              msdos
             vfat
             iso9660
nodev   nfs
             reiserfs
nodev   devpts
nodev   usbdevfs
nodev   usbfs
             udf

well now it has udf because i tried modprobe udf
and that put it there. but still cant mount a dvd

keefaz · 04-27-2005, 07:48 AM

Have you dvd+rw-tools package installed ? If not, install it, put the dvd
in the drive and post the output with :

dvd+rw-mediainfo /dev/hdb

f34r7h1s · 04-27-2005, 07:54 AM

this is the output of that command you said

Code:

# dvd+rw-mediainfo /dev/hdb
INQUIRY:                [MATSHITA][CD-RW  CW-8121  ][AW22]
:-( unable to MODE SENSE#2A: Input/output error

and i would need Dvd+Rw even tho its not a dvd burner?

f34r7h1s · 04-27-2005, 11:14 AM

Sooo... after countless hours of trying to figure it out.. I can mount factory pressed dvds. (well at least my XMen movie) I cant read Data Dvds period.... I can read movie dvds (burned and bought)... donno

lol help still wanted

strandjd · 04-27-2005, 01:51 PM

I finally got my DVD/CDROM combo drive working! Thanks to the many posts out of here.

The lines in my fstab may not be optimal, but I can read CD's and DVD's.

/dev/cdrom /mnt/cdrom auto defaults 0 0
/dev/cdrom /mnt/dvd auto defautls 0 0

This seems to be working for me. I have a Gateway Solo 5350 with the CD-RW/DVD combo drive and Slack 10.1.

Hope this helps!

-John

f34r7h1s · 04-27-2005, 03:01 PM

yeah i dont know... its still not working for me (changed it to what you had but nothin)

So as a total over all recap, after trying all the suggestions said to me

I have a dvd Cd-rw combo drive, i can read cds and dvd movies. But i cannot read Data dvds.
dont know why.

Thank you to all have helped me so far and thank you to whoever will continue to help
