Playing a CD With Hdd Install

[Kowood]

Am I using /etc/fstab wrong? Because when I put it in, under root user, it just says something about it not being a command. /cdrom dumps me to the hard drive, not the cdrom.

Just to throw my hat in,
I had a problem with this same type of issue on my Hd install. How I got aroung it was by deleting the desktop icon for the cd rom on my desktop. I then rightclicked and created a new device. I named it cd-rom and selected the device from the list it provided me. It worked for me. I know it doesn't change the config setting and delve into the core but you may want to try it.

If it doesn't work, sorry can't help.

[Kowood]

The man's got a good idea. It's often the simple things that foul it up.

[Kowood]

Oh, I'm also trying to get Cedega, I already downloaded it in a tar.gz form, but should I have got it the .deb form?

Your problem is the way linux deals with audio (ie not data) CD's. Put in a data CD (perhaps your Knoppix CD) & click on the CDrom icon or navigate to /cdrom & it should open. If you navigate to /mnt, autofs should create /mnt/cdrom which will 'exist' only while the CD is in place & the cd should be accessable there too.

If you're using a "fromhd" Poor Man's Install, navigating to /cdrom will show you the contents of the partition your Knoppix "cloop" image is stored on, not the content of the CD in your CD-ROM drive.

If you then put a data CD into your CD-ROM drive, and navigate to /mnt/cdrom, the automounter should mount it and show you the data. If for some reason it doesn't, you can mount it manually as root to an existing directory in /mnt. For example,

mount /dev/hdc /mnt/test
(Edit: It may be "hdc1" or "hdc", I'm not sure. In my Red Hat Linux experience, I had to create a symlink from /dev/hdc to /dev/cdrom.)

should work if your CD is your secondary master, or, if you passed Knoppix the "hdc=scsi" code so you can burn CDs,

mount /dev/scd0 /mnt/test

should mount a data CD on /mnt/test.

CrashedAgain's and Cuddles' experiences match mine with audio CDs. That is, I get error messages when I try to mount them, but they play just fine in XMMS.

P.S. Not to beat a dead horse, but Kowood, you said you successfully saved a file to the partition you mounted the Knoppix image from, after the "poor man's installation." Please post the output of "cat /etc/mtab" after you go through the steps to make that partition writeable.

It still said mount point /mnt/auto/cdrom doesn't exist.

[Kowood]

Could it have something to do with the fact that it's /mnt/auto/cdrom and not /mnt/cdrom ?

[markleong]

Kowood, do the following as root user in a console:-

cat /etc/fstab

You should see an entry for /dev/cdrom. That should point to /cdrom. Post the output here and we would be able to see your mount points.

BTW, how new are you to knoppix? linux?

Hmmm.
I just tried with my poormans install & I am not able to mount either a data CD or an audio CD when running from the poormans. You are right, /cdrom is the partiton on which the poormans is installed, however when I put either a data CD or an audio CD in the CD drive, the drive light lights for only a moment then stops & navgating to /mnt or /mnt/auto shows nothing. There is a /mnt/cdrom but it's locked & konqueror says it's a 'link to unknown'. It's actually a link to /mnt/auto/cdrom which autofs creates when reading a CD but that doesn't seem to work in poormans.
So maybe there is a problem with autofs in poormans??? or maybe it's particular to my installation since my poormans is actually a poormans install of a remaster & I may have killed something doing the remaster.

[eco2geek]

Dunno, it may be due to your remaster. What do you get when you run /etc/init.d/autofs status? It seems to work OK using a PMI ("poor man's install") of stock Knoppix 3.6.

Here's what /etc/mtab looks like on my PMI:

/dev/root / ext2 rw 0 0
/dev/hda5 /cdrom vfat ro,nodiratime,fmask=0022,dmask=0022,codepage=default,iocharset=default 0 0
/dev/cloop /KNOPPIX iso9660 ro 0 0
/ramdisk /ramdisk tmpfs rw,size=91988k 0 0
/proc/bus/usb /proc/bus/usb usbdevfs rw,devmode=0666 0 0
/dev/hdb2 /mnt/hdb2 ext3 rw,nosuid,nodev 0 0
/mnt/hdb2/knoppix.img /home/knoppix ext2 rw,loop=/dev/loop0 0 0
automount(pid818) /mnt/auto autofs rw,fd=4,pgrp=818,minproto=2,maxproto=4 0 0

Line 2 indicates the partition the cloop file's on (hda5, FAT32). Line 7 is persistent home (hdb2/knoppix.img). And line 8's the automounter.

See how hda5 is mounted read-only? I don't see how you can unmount it and mount it read-write while Knoppix is running. Two people have told me they've managed to somehow save files to the drive their PMI is running from, but this is why I still don't believe them.
