a bit of a brain teaser.. (dvd drive issue)

Re: a bit of a brain teaser.. (dvd drive issue)

Hi All,

Has a resolution for this problem been found? I am having the same issue, pretty much exactly.

Here's are the fstab lines:

/dev/hda /media/cdrom0 auto users,atime,auto,rw,dev,exec,suid 0 0 (old)
/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec 0 0 (new)

Pasting in the new line didn't change the situation.

I had a look at the CDRom under Kinfocenter, and the only thing that it says no to is "can select disk".

I haven't tried the last recommended solution, so was wondering how that worked out before I took the plunge?

Thanks

EDIT: I should mention that I am running an HPDV6500T with a SuperMulti 8X DVD+/-R/RW.

Don't know -- either adding the lines to /etc/modules worked, or else he gave up --- it's hard to tell which.

Why don't you try those, and let us know if either of them works?

Alright, gave it a bash.

Added piix to the modules file: no change
Same goes for adding ide_generic.

I tried with the /fstab altered as you recommended earlier.

Any thoughts on a way forward?

Thanks

Re: a bit of a brain teaser.. (dvd drive issue)

When you go into the BIOS on that computer, where does the optical drive show up -- on the IDE bus, or elsewhere?

Re: a bit of a brain teaser.. (dvd drive issue)

Alright, trying to figure out how to see that. The PhoenixBIOS Setup Utility on this laptop doesn't list anything about the drives. Under Main, I can only toggle between System Data and Diagnostic Log, then there is a Security tab, a Diagnostics tab, and a System configuration tab. The only information about drives is under boot options, which is for changing the order.

I will try figure out this answer from HP.

Back when I have a solution.

Re: a bit of a brain teaser.. (dvd drive issue)

HP is online at the moment. So far they have pointed me to the device manager under Vista, and am waiting on answers for the Bios. I am booted into Vista now, and have gathered the following under the device manager:

Slimtype DVD A DS8A1P ATA Device
Driver Version: 6.0.6000.16386
Hardware IDs all start with IDE
Compatible IDs: GenCdRom
Enumerator: IDE

IDE, I suppose.

Is that useful information?

Re: a bit of a brain teaser.. (dvd drive issue)

Yeah, I think so, except it points us back to the entries in /etc/modules for piix and ide_generic.

I'd say work Mr. Google and maybe Ubuntu Forums a little, with your laptop model number plus that drive model "DS8A1P", and see if you can turn up anything further about it. Since it's not working in the default OS configuration, there probably is a module that needs to be added, but if it's not piix or ide_generic, it must be something else.

Alrighty, will give it another shot in the world of search.

Thanks, and will post progress or lack thereof.

Re: a bit of a brain teaser.. (dvd drive issue)

Well, there seems to be very little out there on this particular drive. I saw some people referring to it directly, but they were on Finnish or Russian fora!

I also something that mentioned Pata_piix, but there weren't enough specifics to really follow. Does that make sense?

Lastly, Ubuntu forums have some things that are tangentially related. One forum blames it on grub, but that was related to a dual-boot in which the DVD/CD was not visible in either Vista or Ubuntu. Not my problem. However, they recommended a fix using Lilo, in this thread: http://ubuntuforums.org/showthread.php?t=528216&page=3

(Relevant text pasted below).

Does this look like a possible solution? I am willing to try it, but don't know how to back out of it if things go cock-eyed. Would it be just a matter of getting into Kubuntu again via Lilo and using the Adept Manager to uninstall Lilo?

Sorry for coming back without having actually tried anything, but I am spinning my wheels a bit here.

Thanks.

Here's the text:

Actually installing lilo will be easier from ubuntu than from the LiveCD. So carry out Step 2) and boot into Ubuntu. (if you copy and paste my code from Step 2, it shouldn't take very long)


To install lilo open a terminal and type:

Code:

sudo apt-get install lilo

Create and open a new file "/etc/lilo.conf" via

Code:

gksudo gedit /etc/lilo.conf &

Copy and paste this into the file:


Quote:
lba32
boot=/dev/sda
root=/dev/sda2
prompt
timeout=50

image=/boot/vmlinuz-2.6.22-14-generic
label="Ubuntu"
initrd=/boot/initrd.img-2.6.22-14-generic
append="ro quiet splash"
read-only

image=/boot/vmlinuz-2.6.22-14-generic
label="UbuntuRecovery"
initrd=/boot/initrd.img-2.6.22-14-generic
append="ro single"
read-only

image=/boot/memtest86+.bin
label="Memory Test+"
read-only

other=/dev/sda1
label="Vista"

Type

Code:

uname -a

in the terminal and make sure "2.6.22-14-generic" appears in the output. If not use the numbers from "uname" in place of "2.6.22-14-generic"

Save the file.

In the terminal

Code:

sudo lilo

Reboot. You should now get a lilo menu in place of the grub menu. And hopefully you can boot into ubuntu and windows and your DVD-drive is working.

Sorry, this simple "lilo.conf" won't give you a fancy boot screen. All I know about lilo I learned today. And I don't want to try anything which might not work.
