cdr/burner problems


hi all. I have a problem. I was running slack 9 with the 2.2x kernel until last week. I messed some stuff up (rather not go into it) so i downloaded a new ISO and installed that. After wrestling with that i got it to work and the kernel is now 2.4. cool.

well not so cool after all.

now everytime i try to mount a cd that i burned, i get this error

bash-2.05b# mount /mnt/cdrom
mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
or too many mounted file systems


i am over this because it mounts cd's and cdr's that burned in my mom's windoz machines just fine. Whats even wierder is that it won't even mount blank cd's.

(btw i have the burner setup correctly because , i can see the lines on the underside of the disk)

any help or explanations would be great.

Lagg.


UPDATE:

I've tried some more cd's. Aparently it's completely random on what works, and what does.

x2!!!!

Maybe it isn't autodetecting that it is a cdrom for some reason. If that is the case then try this command:
mount -t iso9660 /dev/hdc /mnt/cdrom

You might have to change hdc to cdrom. Play around with it.

What does /dev/cdrom (it's a symbolic link) point to?

# Managing drives
LNAG - Accessing my drives
Rute - Device Mounting

# CD burning info
Is it configured and what is the device? Command this to find out:
cdrecord -scanbus

humm

i've tried

mount -t auto /dev/hdc /mnt/cdrom

and i get

bash-2.05b# mount -t auto /dev/hdc /mnt/cdrom
/dev/hdc: Input/output error
mount: block device /dev/hdc is write-protected, mounting read-only
/dev/hdc: Input/output error
mount: you must specify the filesystem type
bash-2.05b#

if i try mount -t iso9660 /dev/hdc /mnt/cdrom it's

bash-2.05b# mount -t iso9660 /dev/hdc /mnt/cdrom
mount: block device /dev/hdc is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/hdc,
or too many mounted file systems


so it has a big problem when it comes to reading stuff.

NOW disks that i wrote usin iso9660 it will read....

Are you trying to mount a music CD which is impossible? Mountable CDs are iso9660.

See the managing drive links for explanations.

Filesystems HOWTO
ISO 9660 - CD-ROM filesystem

How did you burn the CDs. Did you use a pointy-clicky gui front end that can hide error messages or burn directly using cdrecord, the program that all the gui front ends front for?

You will see all error messages when you burn from the command line.
