Thumbs down going in circle's with fstab and cd-rom


I have had nothing but problem's with trying to access my cd-rom.
I get the cd-rom working so I can mount it and access it, then next time I need it, it won't work.
I checked the fstab file, and it was about 20 line's.
I partitoned my drive manually the first time I installed mandrake9.1,
then I re-installed for reason's I don't remember.
I let mandrake partition it this last time. What I have is this:
/, /home, /swap.

I edited my fstab file to look like this:
/dev/hda1 / ext3 defaults 1 1
/dev/hda6 /home ext3 default 1 2
/dev/hda5 swap swap defaults 0 0
/dev/hdc /mnt/cdrom iso9600 ro,exec,auto,user,async 1 0
/dev/fdo /mnt/floppy auto
none /proc proc defaults 0 0
none /dev/pts devpts mode=0620 0 0

restarted, and saw that iso9600 was not supported, so I changed that to auto.
restarted and still no cd-rom access.

My fstab file look's like this now:
/dev/hda1 / ext3 defaults 1 1
none /dev/pts devpts mode=0620 0 0
/dev/hda6 /home ext3 defaults 1 2
/dev/hdc /mnt/cdrom supermount dev=/dev/hdc,fs=auto,--,user 1 0
/dev/hdc /mnt/cdrom2 supermount dev=/dev/scd0,fs=auto,ro,--,user,umask=0 0 0
/dev/fdo /mnt/floppy supermount dev=/dev/fd0,fs=auto,--,user,sync,umask=0 0 0
none /proc proc defaults 0 0
/dev/hda5 swap swap defaults 0 0

How do I properly set this up?
If it was done right, would I be mounting the device's in console?
Someone heeeelp me please.

Perhaps the "auto" is correct with supermount? Usually it is not unless you always boot with a CD in the CDROM drive.
Check any other replys, but supermount is sometimes the culprit for mounting problem with Mandrake. Is it really only your CD or does your floppy have the same problems? If you cannot find another solution and suspect supermount check:
http://www.mandrakeuser.org/docs/res...lm-faq.html#4f
I am not at all sure that supermount is or is not a problem with the newer releases.
Good Luck.

Nah, sorry "2dc",

the supermount should work fine in 9.1

chopp doesn't say what he/she is trying to mount i.e. music cd's or data

If it's data, then it SHOULD just be accessible when the disc has been put in, if it's music, then the default /dev/cdrom often doesn't work and would have to find out what else the device is called i.e. if it's a burner, then it's often called /dev/scd0 (a la scsi emulation) though it could also concieveably be something like hdb or hdc (like my original debian install did, as I didn't know that it wouldn't detect my device as a burner and automatically choose scsi emulation).

regards

John

I will be glad to give up harping on this then.
I ran 8.0 and had to shut it down as described in the a.o.l.mandrake FAQ. I was a little put out that I had to go there rather than finding it listed as eratta on the Mandrake site. I have heard people complain about it in other releases and had someone deny I could of had a problem with it in 8.0
My understanding is that it happened/happens sometimes but not to everyone.
Anytime I see someone posting "weird" mounting problems with Mandrake I have posted a link to the FAQ. Other posibilities should be investigated first.

I seem to recall something about the supermount being a problem with some systems as late as the 9.0 release - though that seems to have faded into the distance with 9.1 and the early 9.2's

Joke is though, since having snags doing the "debian thing" I've now got into recommending knoppix first - and if [they] can run that from disc and get net access with it, then install it to [their] hard drive. I saves one hell of a lot of problems that can result in n00b types trying "proper" debian (as originally said by the Welsh comedian Max Boyce "I know, cos I was there"! ).

regards

Heh, heh, heh.
I would still recommend Mandrake, Suse, Red Hat to newbies. Although Slack and Debian are not that bad, and many people start with them, I do not suggest them as a first distro.
I also think recommending Knoppix is a great idea. I think almost everyone but Bill Gates agrees with that.
Perhaps I should check at a.o.l.mandrake for current supermount opinions.

What I have is a laptop, with an external usb cd-rw. I got rid of the supermount thing and still no go.
What I have on my desktop is this:
Floppy mounted at /mnt/floppy
CD-ROM (hdc) (not mounted)
CD-ROM (scd0) (not mounted) with a exclamation mark on the icon.
The floppy work's just fine.

thank's so far guy's.

cdrecord -scanbus

/dev/hdc /mnt/cdrom supermount dev=/dev/hdc,fs=auto,--,user 1 0
/dev/hdc /mnt/cdrom2 supermount dev=/dev/scd0,fs=auto,ro,--,user,umask=0 0 0


BTW its iso9660 instead of iso9600

You have two lines. Do you have a cdrw too?
If you want to keep supermount the entry for the CDROM should be:

none /mnt/cdrom supermount dev=/dev/hdc,fs=auto,--,user 0 0

You should also be able to ignore fstab and mount a CD if you log in as root:
mount -t iso9660 /dev/hdc /mnt/cdrom

Sorry, neglected to mention the laptop external burner thing.

/dev/hdc /mnt/cdrom2 supermount dev=/dev/scd0,fs=auto,ro,--,user,umask=0 0 0

Should be:
none /mnt/cdrom2 supermount dev=/dev/scd0,fs=auto,ro,--,user 0 0

umask=0 would be for allowing users to read / write which you can't do on a CDRW yet. I believe that udf support i.e packet writing is in the 2.6 kernel

Did you try the CDROM yet?

I believe a USB CDRW would use USB mass storage.
If that is correct it is a matter of having the correct kernel modules, Lilo addition, and perhaps device links.
So first, are you using Lilo as the boot manager, and second, can you post the outout from ' lsmod'?
I think you need to have "ide-scsi","usb-storage", "usb-uhci", and "usbcore" modules listed.

michaelk, I just tried both CD-ROM (scd0) which is the cd-rw, and CD-ROM (hdc) which is the cd-rom. They both work!!
Is that how they both should show up on the desktop?
What is the proper way to mount either of these device's from console? And how the heck did my fstab get so messed up before?

thank's

I have no clue on how they would of gotten messed up.

You have your choice
mount /mnt/cdrom
or
mount /dev/hdc

The same holds true for the cdwriter using its folder or device.

Mandrake usually creates a removable mediafolder on the desktop of which there should be another folder for your floppy and CDROM

If the USB writer was not plugged in during the install it would of auto configured it the first time you plugged it in.

When you click on a folder konqueror should open up a window with the contents of the drive.

You can always create a folder that points to the CDROM or CDwriter if MDK failed to.
