Re: Non-coder contribution: hardware testing

[Paul DeShaw]

Hello,

I saw this tab open in my browser and it had a workaround:

https://answers.launchpad.net/ubuntu/+question/49921

It said to switch the jumper on the drive to "cable select".  I can't
find the message that sent me that link; but I think it was someone on
ubuntu-studio-users; or else it was a link from one of the pages from
Kirko's links.  I noticed in the above Launchpad question that Ubuntu
Studio was not mentioned, so maybe it is more general.  Puzzling that
Ubuntu can find the drive when booted from a USB stick.

Back to Ubuntu Studio 10.04 booted from the hard drive: The CD/DVD
drive still does not appear in the Places menu, but it is in
Places>Computer.  If I put an audio CD in, Audio Disk appears in both
the Places menu and the Places>Computer file browser window.  If I
right-click on the Audio Disk in the Places menu, I get this error:
"Could not open location 'cdda://sr0/'
 Failed to exexute child process "sound-juicer" (no such file or directory)"

Right-clicking in the Places>computer file browser window opens a
normal contextual menu.

If you want to change any of this behavior, I am willing to test
patches.  I was led to believe that the "slave" jumper setting was
standard, which is troubling...if that's how most people's drives are
set up, there could be a lot of Ubuntu machines without working HP
840d drives.

I have an ECS motherboard with an AMD 64 processor (2800+ ? not sure)
and ATI Radeon built-in graphics.  If you want more detail, please ask
and I'll try to track it down.

Thanks,

Paul in Seattle

Re: Non-coder contribution: hardware testing

[Ricardo Lameiro]

ok, lets see if your computer /kernel can "see" the cd drive.

please issue the following command on you home folder :

$sudo lshw > hardware.log

if you dont have lshw, just do $sudo apt-get install lshw

lshw is a tool that list all the hardware components in you computer, from
here we maybe can have some point to start off.

Explanation of of the command:

Sudo - run the following command as a super user

lshw - list hardware devices

> hardware.log  - outputs the information to a file (hardware.log), instead
 of outputting it to the screen (stout).
You can run this command and check the results on the CLI screen.

After that attach the file and we will see then.
