 |
|
Hey guys and gals I am having some issues here with My CDROM. now before you jump on the whistle and say look here for the instructions hear me out
All of my Optical Disks work! Yes all Three of them
Here is my fstab
| Code: |
# <fs> <mountpoint> <type> <opts> <dump/pass>
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/hda1 /boot ext3 noauto,noatime 1 1
/dev/hda3 / ext3 noatime 0 0
/dev/hda2 none swap sw 0 0
/dev/cdroms/cdrom0 /mnt/dvd iso9660 noauto,ro,user 0 0
/dev/cdroms/cdrom1 /mnt/cdrw iso9660 noauto,rw,user 0 0
/dev/cdroms/cdrom2 /mnt/cdrom iso9660 noauto,ro,user 0 0
/dev/fd0 /mnt/floppy auto noauto 0 0
# NOTE: The next line is critical for boot!
none /proc proc defaults 0 0
# glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
# POSIX shared memory (shm_open, shm_unlink).
# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will
# use almost no memory if not populated with files)
# Adding the following line to /etc/fstab should take care of this:
none /dev/shm tmpfs defaults 0 0

I have tested the eject command on all the drives.. they work
I have tested functionality on the CD ROM with an Audio disc with Gnome CD player, and It works, however I had to say look here in /dev/cdroms/cdrom2 and voila it works
here is my /mnt dir
| Code: |
savage@devel savage $ ls /mnt -al | more
total 24
drwxr-xr-x 6 root root 4096 May 5 20:29 .
drwxr-xr-x 20 root root 4096 May 3 08:29 ..
-rw-r--r-- 1 root root 0 May 6 16:30 .keep
drwxr-xr-x 2 root root 4096 May 1 11:42 cdrom
drwxr-xr-x 2 root root 4096 May 5 20:29 cdrw
drwxr-xr-x 2 root root 4096 May 5 20:29 dvd
drwx------ 2 root root 4096 May 1 11:42 floppy
|
However when I try and mount the cdrom ( /dev/cdroms/cdrom2 )
I get this error ...
| Code: |
savage@devel savage $ mount /mnt/cdrom
mount: wrong fs type, bad option, bad superblock on /dev/cdroms/cdrom2,
or too many mounted file systems
|
all the other drives mount and umount so I dont know why this is happening
In order I have my Drives set up as follows
Secondary Master is the CDRW
Secondary Slave is the CDROM
Primary master is the Hard drive
Primary slave is the DVD-ROM
I enabled ide-scsi in the kernel as a module and still the same effect
Any Suggestions??? 
Thank you in advance
regards sAvAgE

Have you checked the IDE cables? Stating the obvious I know but it's the easiest to check/fix!
The disc that you are trying to mount in /mnt/cdrom, does it mount Ok in the other drives?
Are you using UDEV or DevFS? Are /dev/cdroms/cdrom? symlinks and do they point somewhere sensible? |

Yes I have checked the cables, and also I checked the BIOS and everything seems ok. I tried a quick test where I put in the bootable ISO of GENTOO 2004.1 the computer booted and read the disc.. however Gentoo itself could not load the disc. it kept trying to scan for the device where it came from.
yes I can
| Code: |
mount /mnt/cdrw
mount /mnt/dvd
mount /mnt/floppy
umount /mnt/cdrw
umount /mnt/dvd
umount /mnt/floppy
eject /mnt/cdrom
eject /mnt/dvd
eject /mnt/cdrw

| How about the symlinks? Do they seem to point to sensible devices? |

you could try setting the iso9660 to auto...

To check the symlink links:
| Code: |
ls -l /dev/cdroms/*
|
symlinks will appears something like:
| Code: | lrwxrwxrwx 1 root root 6 May 9 15:43 cdrom -> ../hdb
lrwxrwxrwx 1 root root 6 May 9 15:43 cdrom0 -> ../hdb
lrwxrwxrwx 1 root root 6 May 9 15:43 cdrom1 -> ../hdd
|
If your writer is setup as a SCSI device then it will be pointing to something like ../sg0
Although, after re-reading your original post, it sounds like /dev/cdroms/cdroms2 is pointing a block device but which???
You can try changing the FS from iso9660 to auto but if you have managed to mount the same CD in two drives but not the third, it would seem that the disc is ok and contains a valid iso9660. |
