can't mount new cd drive - changed recently...

Hi all! 

Few days back I've changed my cd drive (was working ok, but was "borrowed" from another machine".  Now, the new cd drive wan't mount. It locks up whole system and the only thing I can do  is to hard reboot by reset button.

Lines in my fstab is standard:
/dev/cdroms/cdrom0     /mnt/cd   iso9660   ro,user,noauto,unhide   0      0
/dev/cdroms/cdrom0     /mnt/dvd  udf       ro,user,noauto,unhide   0      0

So, on:     mount /dev/cdroms/cdrom0        after 5-10 sec. machine waits ... and locks up completely.

Anyone with a gentle piece of advice to sort out this thingy?

Cheers, :?

Perhaps you have no power to the CDrom as presently installed...

Another possibility, a bent pin in the IDE cable socket...

A master vs slave jumper issue?

Re: can't mount new cd drive - changed recently...

my bad :oops: - I should have been more clear:

it does have power, since I can have it open, close and spin, heh. Also, I'd say plug pins are fine and it's a master on its own ide(1) and bios finds it ok. I think problem could be that arch somehow doesn't know that I've changed it and uses (???) other setings to try to read it. If that's the case, I'd need to change that. How? .....  OR, is it something else? In any case, it might be a good time to buy new cd drive.

Thanks and cheers,
mladen

Re: can't mount new cd drive - changed recently...

What does "dmesg | grep hd" say?
Put a CD in.  Does the "eject" command work (if installed)?
Do audio CD's work (since no mounting is required)?
Any errors in /var/logs/messages (etc)?

And unrelated:  wouldn't it be shorter to type "mount /mnt/cd"?

Hey kpiche, thanks for bearing with me!

dmesg | grep hd  says nothing.
Eject does work (as su).
Haven't tried audio, since I don't use this machine for any multimedia.
No errors in /var/log/kernel    (arch was logging this type of messages here by default). These are some interesting  log lines - everything just fine, I'd say:

Re: can't mount new cd drive - changed recently...

No prob.  Not sure now.  It's obviously recognized by the kernel.  You could try mounting using /dev/hdc directly:

mount /dev/hdc /mnt/cd

Check that /dev/hdc and /dev/cdroms/cdrom0 point to the same device (don't see why they wouldn't).  Mine:

# ls -l /dev/hdb
lr-xr-xr-x  1 root root 30 May  8 15:22 /dev/hdb -> ide/host0/bus0/target1/lun0/cd
# ls -l /dev/cdroms/cdrom0
lr-xr-xr-x  1 root root 33 Dec 31  1969 /dev/cdroms/cdrom0 -> ../ide/host0/bus0/target1/lun0/cd

Try another CD.

No ideas after that.   :?

Re: can't mount new cd drive - changed recently...

hmmm... all's fine... Looks to me I'll have to buy real new cd rom. This problematic one is 6 year old. Probably some 2.6.5 kernel issue (worked on 2.4.x). Go figure.

Thanks and cheers,
