Help with Fstab


Could someone help me configure my fstab file to work with all my devices? I am running a special flavor of Slackware called Topologilinux (runs off an image file, but boots into "real mode"). I have 1 hd partition (windows), which it recognizes fine. I have three cd drives, a usb external CD-RW drive, which it recognizes because I had set that as my main drive during setup, an internal DVD+RW drive, and an internal CDROM. The internal CDROM and DVD+RW drive aren't recongized. I tried modifying fstab, but I'm not sure if I'm doing it right. What specifically should I put into fstab (and where) to mount these 2 cd drives? Here is my fstab file:
Quote:
# Format:
# <file system> <mount point> <type> <options> <dump> <pass>

# This is for a loop device as root linux system.
/dev/loop7 / auto defaults 1 1

# the CD and the floppy
/dev/cdrom /mnt/cdrom iso9660 users,defaults,noauto,ro,user 0 0
/dev/fd0 /mnt/floppy auto users,defaults,noauto,user 0 0

# proc file system:
proc /proc proc defaults 0 0

# Unix98 devpts filesystem:
#none /dev/pts devpts gid=5,mode=666 0 0

# This is a loop device swap file
/dev/loop6 none swap sw 0 0

#if you have other partitions you want like windows partitions
#add it below here
/dev/cdrom2 /mnt/dvd-rw iso9660 users,defaults,noauto,user,ro 0 0
/dev/cdrom3 /mnt/cdroma iso9660 users,defaults,noauto,user,ro 0 0
As you can see the last 2 lines are my attempts at modifying it to recognize the cdroms, it didn't work.
Any ideas?

what errors do you get when you try to mount a cd ?
try : mount /mnt/dvd-rw
and : mount -t iso9660 /dev/cdrom2 /mnt/dvd-rw
( you'll get some output...)

and do these mountpoints exist ( like /mnt/dvd-rw ) ?

and do you have 3 cd-drives ?

Yes, I have 3 cd drives.
How do I create that mount point to begin with?
Here is my error:
Quote:
mount /dev/dvd-rw
[mntent]: warning: no final newline at the end of /etc/fstab
mount: can't find /dev/dvd-rw in /etc/fstab or /etc/mtab
I'm just not sure where to begin when adding new devices. When I use knoppix or slax it auto detects these drives.

Could you post the results of "dmesg | grep cd"
That should give us the device names they are being pinned to. Then we can get your fstab table setup.

-------------endquote

well....i suggested :mount /mnt/dvd-rw
an entry " /dev/dvd-rw " is not in the fstab ( so that's an error.)

first: make the 2 mountpoints ( they are just 2 empty dir. ) : " mkdir /mnt/dvd-rw " ( you can guess the other )

then do as ringwraiht suggests to find the device-names.
post it here if you need any help in writing the fstab-lines.

Here is dmesg | grep cd... it doesn't look like much help though:
Quote:
dmesg | grep cd
hdc: attached ide-cdrom driver.
hdd: attached ide-cdrom driver.
ehci_hcd 00:02.2: nVidia Corporation nForce2 USB Controller
ehci_hcd 00:02.2: irq 5, pci mem dcb18000
ehci_hcd 00:02.2: USB 2.0 enabled, EHCI 1.00, driver 2003-Dec-29/2.4
cdrom: open failed.
cdrom: open failed.
cdrom: open failed.
cdrom: open failed.
I also tried mount /mnt/dvd-rw, same result.
Any ideas on what I should write for fstab?

------
/dev/hdc /mnt/dvd-rw iso9660 users,defaults,noauto,user,ro 0 0
/dev/hdd /mnt/cdroma iso9660 users,defaults,noauto,user,ro 0 0
------
those lines should look smth. like that.
but i saw only 2 cd-drives in the dmesg-output ( hdc &hdd )
( i think the dvd is missing )

if you plan to play dvd's it's best to make that drive hdc ( =master on second ide ).

look in the /dev directory for hd? devices ( you'll have hda as harddisk, and there should be hdb,hdc,hdd )
also there will be at least a /dev/cdrom, wich is linked to hdb -c or -d.
( that one is the drive used by the first fstab line )
the other 2 devices should be used in the other 2 lines.
and make the mountpoints as said before.

don't understand this " cdrom: open failed ", but first get the fstab correct, and then solve the rest

sorry it took me so long to get back to this. I made the directories at /mnt/dvd-rw and /mnt/cdrom1, but it still doesn't seem to be working. The Knoppix Live-cd (and Slax for that matter) recognize all of them. Could I just copy and use that part of their fstab file in my hdd install one?

yes, i think you can copy the lines right into the other fstab, but make sure the mountpoints ( = /dev/cdrom1....etc.) exist.
