I have a data cd in the dvd drive. I tested the cd with my cdrom first to ensure that it was good (and it is). When I issue the command I receive the message

. I am running kernel v. 2.6.3.12 and Slackware 10.1.

Perhaps the fstab file is incorrect?
To the best of my knowledge the drive is working.

Any help is appreciated.

On the /dev/dvd line change iso9660 to auto. If that doesn't work you may need to load the udf module.

modprobe udf

I tried changing iso9660 to auto but it didnt seem to help.



As root:

# modprobe udf
# FATAL: Module udf not found

I checked my .config to see if I compiled support for udf into my kernel and I did.
I didn't compile it as a module, perhaps I should have.

Suggestions?

Is the dvd your trying to mount blank if so you cant mount blank media. You might have made a coaster too. I dont know of any other filesystems dvd's use other than udf,iso9660

No it wasnt a blank dvd, Ive tried the unreal tournament 2004 dvd and a few data cd's.

I am thinking maybe the drive doesnt work properly anymore.

Maybe someone can tell me if this test is valid.

In my CMOS I have cdrom as bootable drive (Does this include dvd drive ? or is there another option I should enable) .... anyways I put a bootable disk in the cd burner that I have and it booted off the cd like it should... I put the same cd in the dvd drive and restarted but it didnt boot off the cd.

Maybe there are some other tests I could try ...

any ideas?

Some pc's can't boot from secondary ide channel like mine some can.

Is it a very definite message from the OS that there is 'No medium found' when you use the mount command (does the error appear right away is what I mean), or does the drive choke on the disk for a few sec/min before spitting out the error?

If it is the latter (and maybe if it is the first as well), you may want to try putting a CD-ROM cleaner in and let it spin for a bit. Could be that the lens has a piece of dirt on it. If you don't have a CD-ROM cleaner, you could take the drive out of your computer, take the cover off of the drive, and use a cotton swab (or a Q-Tip) with some rubbing alcohol to clean the lens. If you go that far, you can grease the gears and rods that the laser rides on as well for good measure.

If you want to test the drive, you can use a boot disk and see if the drive works under that environment (Win98 bootdisk would be a good choice). You could also use a bootable diagnostics disk. The Ultimate Boot CD (http://www.ultimatebootcd.com/) has a large number of diagnostics on it, including one called PC-CONFIG. PC-CONFIG has a CD-ROM benchmarking tool that should check the drive. If thats all you want, there is a link for a DOS boot disk for the utility here....

Hope you can solve your problem.

It happens almost instantly. I do find it hard to believe that the drive isnt working since it was working just fine a few months ago when I had windows on it. And since I used it to install the first part of slackware.

Actually now that I think of it... it was a strange thing that happend. I booted from the dvd drive
(at least I think I did.. my memory might be tricking me) and it loaded into the preinstallation part of slackware (where you make partitions and what not). Then when you choose the source for installation I couldnt choose the dvd rom. It claimed it couldnt find anything to do with an installation on the disk. So I took it out and put it into my burner and it installed it from there with no troubles.

The dvd drive did work with Slack 9.(something) and 10.0


But in anycase like you say it could have some dust in there or something. Perhaps I shall take a look. The warranty is already up anyways now I think.
