[gentoo-user] undetected DVD r/w device

[alain.didierjean]

For some unknown reason, my DVD r/w device is not detected as such by udev:
I can mount /dev/hda and read a data CD, but /dev/cdrom is not created at boot
time and k3b returns
" No optical drive found.
K3b did not find any optical device in your system.
Solution : Make sure HAL daemon is running, it is used by K3b for finding
devices."
Well, hald IS running on my hardened amd64 system and /etc/udev/rules.d contains
 70-persistent-cd.rules. Where should I look now to fix the problem ?

What's the contents of 70-persistent-cd.rules?  I recently had the same
problem on a HP laptop; the DVD drive worked in most things, but not in
K3B, and I tracked the root down to the fact that while I could see
/dev/sr0, the symlinks for /dev/[cdrom,cdrw,dvd,dvdrw] weren't there.  I
could mount /dev/sr0 and the drive worked, but K3B never found the
drive.  I believe I fixed it by editing that rules file somehow.  I
can't remember while laptop it was on, but here's the two
70-persistent-cd.rules files I have:

(I think this one was the one that worked)

# This file was automatically generated by the /lib/udev/write_cd_rules
# program, run by the cd-aliases-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and set the $GENERATED variable.

# CDDVDW_TS-L633N (pci-0000:00:1f.2-scsi-1:0:0:0)

Current kernels usually call optical drives /dev/sr0 (/dev/sr1, &c).

See last months "DVD borked: SysFS removed" thread:
http://www.gossamer-threads.com/lists/gentoo/user/216290

My advice in that thread applies also to you.

I now use the following udev rules (70-persistent-cd.rules)

symbolic links get created, no /dev/sr0. k3b still refuses to work.
BUT
when I
# mount --bind / temporary
I do get a /temporary/dev/sr0 !!
What give ? I'm reluctant to add a NAME=sr0 rule as it should be the default;
What's going on ?

AFAICT, you didn't say if you read the earlier thread cited by Stroller:

No, it wouldn't if you didn't bother to read it or actually follow its  
advice.

Where is the the output of `dmesg`? You have not sent it.

Deselect that which is deprecated and will be removed soon and select the 
appropriate SCSI drivers for your drives.  There's been a few messages on this 
list explaining how to go about it.

Glad you solved it!

My permissions are:

$ ls -la /usr/bin/cdrecord 
-rws--x--x 1 root root 314352 Jul 22 16:51 /usr/bin/cdrecord

$ ls -la /usr/bin/cdrdao
-rwxr-xr-x 1 root root 569352 Jul 22 16:55 /usr/bin/cdrdao

and I had to add my user to the cdrom group, but both of the above binaries 
are not in the cdrom group.

Not needed for cdrecord as you noticed with your test already.

I hope it won't. I have one box whose drives the new drivers cannot

Apparently, though unproven, at 20:24 on Saturday 11 September 2010, Peter

That's the beauty of Linux. When Linus decides he's had enough keeping old 
stuff hanging around and rips it out, you just put it right back in your own 
copies.

Hmm. Not sure how I'd do that. I'd just assumed that I'd stick with a 
kernel version that worked. You know: mask anything later than version 
99.94. And yes, I do remember that version, but in the 1.n.n series.

Is it possible to create one's own patch for drivers from old kernel(s) and 
use that to patch later versions?!  O_O

That seems very odd.  Is there something exotic about those drives?

The new driver sees the controller but the controller doesn't see
the drives?

Or, if the kernel doesn't see the controller then maybe consider
adding the SATA_AHCI driver as a test.  I'm still a bit confused
when trying to figure out which controller uses which driver, but
I've been tripped up with that particular driver before.

Nothing at all. Bog-standard IDE disk and ATA CD-ROM in a Compaq Evo P4 
box. The disk controller is an Intel 82801DB ICH4 according to lspci.

Grub (or do I mean init?) can't find a kernel to boot.

I think the box predates AHCI, though it may be worth a try. I don't 
remember now which options I did try when I was trying to get the new 
kernel drivers to work.

Yes, me too. I have one box on which I had to switch AHCI off in the BIOS 
to enable the installation CD to boot, then back on again to boot the  
installed system.

If you call cdrecord (release 3.00):

	cdrecord -scanbus

or
	cdrecord -checkdrive

and it finds a drive, then there is a bug in k3b.

This looks fishy ...

On mine it is:  Using dev=1,0,0.

This is the result of having a non-orthogonal driver model for SCSI devices in 
Linux.

Some drivers are fully integrated into the SCSI sub-system and receive low SCSI 
bus numbers from libscg and other drivers are separated and are mapped to high 
SCSI bus numbers. Some drivers are even accessible from two or more competing 
drivers.
