Create a symlink from /dev/dvd to /dev/sr2

[rrfish72]

Now this is what I get:

root@0[knoppix]# ll /dev/scd[01]
-rw-r--r-- 1 root root 0 Sep 4 19:36 /dev/scd0
brw-rw-rw- 1 root cdrom 11, 1 May 30 2001 /dev/scd1

root@0[/]# ls -la /dev/cdrom*

I don't know what was done but I'll try it.

DVD drive still works right but cannot even read a data disc with cdwriter (cdrom).

[Markus]

rm -rf /dev/cdrom /dev/cdrom1
ln -s /dev/scd0 /dev/cdrom
ln -s /dev/scd1 /dev/cdrom1

root@0[knoppix]# ll cdrom cdrom1 dvd
ls: cdrom: No such file or directory
ls: cdrom1: No such file or directory
ls: dvd: No such file or directory

Try ll /dev/cdrom /dev/cdrom1 /dev/dvd /cdrom /cdrom1 /dvd

If the dvd works don't touch it

Why weren't the sr#'s needed? I see you bypassed that.

That's it. Everything works now. Thank you very much again for you help.

Looking good.

It was just another symlink causing cdrom->sr0->scd0 , no point in having sr0 in the middle when you can go cdrom->scd0

That's it. Everything works now. Thank you very much again for you help.

No problem, and thank Cuddles instead for doing all the groundwork

[Cuddles]

Thx Markus for the assist, I was starting to see the "trees" individually, instead of the "forest"...

RRFish72 - Kewl to hear you got it "ALL" working now, funny that the install got it all wrong, in the first place - mine just needed a "small" amount of "tinkering" to get my devices working...

Hehe, I spoke too soon. The group is supposed to be cdrom, owner can be root. So this is still needed:
chgrp cdrom /dev/cdrom /dev/cdrom1
You should also check / with
cd /
ll
If needed do:
chgrp cdrom /cdrom /cdrom1 /dvd

I guess so. Now the cd writer does not work again. What happened after a reboot.

What the.... did you do a knoppix or beginner style install which overwrites the devices on a reboot?
BTW, your / is fine.
I'm at work now, I'll look into it after getting home, unless someone has a fix for recreation of the removable devices.

[rrfish72]

I did a knopix style. Why is that important?

[Cuddles]

Markus,

I am going to guess that the etc/fstab needs to be changed, and then all the symlinks, again...

Unless, you know how to disable the autoconfig thing, or get his autoconfig to re-create it all correctly each time... ( ? )
