Ubuntu is running from a CD-RW media, so the drive is locked, the media
cannot be changed in LiveCD mode.
Thanks for all the testing and raising of bugs you've been doing! It's
greatly appreciated :)
This one isn't really a bug, it's a feature :) Really, if you're
running off a live CD, A:
How else would you try whether a laptop is Ubuntu Friendly than
running the tests from LiveCD? I think this is quite reasonable
scenario. For example sombody wants to buy a laptop which was not tested
befor in Ubuntu Friendly program and asks for a couple of minutes or
half an hour to test it.
Maybe running /usr/share/checkbox/optical_read_test and posting its
output here would give a better idea of what's going wrong?
If you could I think it'd be interesting information to have.

As I mentioned, making a bootable USB stick and booting from that. I
don't carry CDs when I go laptop shopping, I carry a USB stick.
You can create one using Startup Disk Creator from the app lens (search
for USB and you should find it). It takes the very same ISO you made
your CD from and puts
Maybe it is worth mentioning here the Plop Boot Manager project from
http://www.plop.at/en/bootmanagers.html which makes it possible (among

this.

Still running from LiveCD:
root@ubuntu:~# /usr/share/checkbox/scripts/optical_detect
Optiarc DVD RW AD-7543A
root@ubuntu:~#
I had a closer look on optical_read_test script. I added some debug
messages, as you can see in the attached patch.
I found that:
- the empty space in /tmp is completely eaten up by cp command
- the return value of cp command is not checked
- compare_tree() fails because of the previous
can you provide the following console output:
ls -l /dev/sr*
ls -l /dev/cd*
Also, do you have a CD-ROM, or is it a CD-RW or DVD-RW drive?
What happens when you insert a data disk? Does the OS open a file
browser or give you any indication that the disk was mounted?
** Changed in: checkbox
Setting this to Low for now as this is the first instance I'm aware of
where an optical drive wasn't accessible via /dev/sr0, but if those do
exist, then it's worth considering for Ubuntu Friendly purposes.
