mounting ide-cdrom fails

[borges]

Hello,

while booting fedora I get the message:

[code:1]
starting smartd: hda: attached ide-cdrom driver [FAILED]
[/code:1]

trying to mount it in the shell, I get the following (german):

[code:1]
mount /mnt/cdrom

mount: Falscher Dateisystemtyp, ungültige Optionen, der
»Superblock« von /dev/cdrom ist beschädigt oder es sind
zu viele Dateisysteme eingehängt
[/code:1]

which is, "mount: wrong file system type, invalid options, the "superblock" of the cdrom is corrupted or there are mounted too many file systems."

it doesn't depend on which cdrom I use; I get it every time...
what could it be? I definitely have no idea...

please help a linux newbie!
:(

thx

Type "df" before ya do that and make sure it's not mounted already. If it's not, then what's it say about /mnt/cdrom in /etc/fstab? Because simply running "mount /mnt/cdrom" is gonna cause mount to check out fstab to see if it sees anything about that mount point.

Alternatively ya could just do "mount -t iso9660 -o ro /dev/cdrom /mnt/cdrom". Or something like that anyway.

it is not mounted already;

there is the follwoing entry in fstab:
[code:1]/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0
[/code:1]

mount -t iso9660 -o ro /dev/cdrom /mnt/cdrom results in the same error message.
And, as I said, there is an error already at boottime.

Seems like a hardware problem, doesn't it? Is there any way to check that?

edit> booting from cd-rom (knoppix) works, just tried it.

Hmm, yeah, that smartd error is kinda strange. what ide channel is your cdrom on? Try turning smartd off and seeing what happens maybe. Seems to me like smartd is only for hard drives anyway. Also, what kinda things does "dmesg" say about your cdrom drive? Oh, and make sure that /dev/cdrom actually exists. If not, you may need to change that to something like /dev/hdc in /etc/fstab.

[borges]

I turned smartd off by interactive startup, but nothing changed.

the dmesg output is:

[code:1]
...
hda: attached ide-cdrom driver.
hda: ATAPI 48X CD-ROM drive, 128kB Cache
Uniform CD-ROM driver Revision: 3.12
...
[/code:1]

/dev/cdrom exists.

:evil:

Maybe I lost some drivers or something... dunno... Just no idea

oh, and: shortly before the bootup error message i get the message: "automount: no mountpoints defined"!

[feenixx]

does the mount point /mnt/cdrom exist? (check /mnt directory)

if you have multiple cd drives, check that they aren't defined to
use the same mount point in fstab.

does command 'mount cdrom' output same message?

[borges]

hi feenix,

/mnt/cdrom exists, and I have only one cdrom drive.

'mount cdrom' is not defined ("could not find cdrom in /etc/fstab or /etc/mtab").

Ok, just tried a bit more:

Mounting only fails with audio cdroms!

When I mount a usual data-cd, i get

[code:1]
udf: registering filesystem.
UDF-fs: No VRS found
[/code:1]

after that, the cd is mounted!

Mounting a audio cd in the shell (without x), I get these additional errors:

[code:1]
hda: command error: status=0x51 {DrieveReady SeekComplete Error}
hda: command error: error=0x54
end_request: I/O error, dev 03:00 (hda), sector 64"
[/code:1]

and so on (thus several times)

Can anyone just give me some hint what could be going wrong/what I can look at/configure? I'm not very experienced with Linux.


Thanks

I don't think you mount audio only CD's. Mounting is for CD's with a file system and data (including mp3's). Of course I'm pretty new to Linux so I could be full of it.
