Burning CD or DVD from command line: Can't find device!

rm_-rf_windows · 06-28-2007, 04:49 PM

I've been reading an excellent tutorial on burning CDs and DVDs from the command line. Here it is:

http://howto-pages.org/cdwriting.php

I've figured almost everything out - really an excellent tutorial for a beginner... - iso images, mounting and reading the files and directories in the iso file, etc.

I'm having trouble identifying the location or coordinates of my CD/DVD burner/player device:

Code:

When I try to simulate a burn using dev=1,0,0, and some other possibilities (ridiculous choices, but I was getting a bit frustrated!), I get the following:

Any idea what I need to do to get this simulation working?

And, what's the difference between TAO and DAO? How do I specify which one I want? What's the best choice here? Any other suggestions?

dive · 06-28-2007, 05:04 PM

Have you tried dev=ATAPI:1,0,0 or even dev=/dev/hdc if hdc is your cd burner?

dive,

We're getting there! I did a variant on your suggestion:

How do I change from TAO to another mode? Is DAO what I want? Or something else?

Thanks for the very swift reply!

dive · 06-28-2007, 06:04 PM

Try DAO or SAO. Depends on what you are burning too. For an ISO use DAO. Or even try CDRDAO program - it's made just for burning images.

Cool! It all works! What do you make of the three warning messages?

Thanks man!

dive · 06-28-2007, 06:53 PM

The first error pops up because of the way that the device is addressed - i.e. /dev/xxx - it's unsupported but works. Did you try dev=ATAPI:1,0,0 (since the scan command reported atapi device)?

The other errors are disk/media errors. Could be bad media.

rm_-rf_windows · 06-28-2007, 09:34 PM

The above is from my Mandriva box. I just tried it on Debian, and it's slightly different. "-J" didn't work, I had to use "-joliet-long" instead. I tried using "dev=ATAPI:0,0,0" and it said to use OLDATAPI, so I used "dev=OLDATAPI:0,0,0" and it worked... Well, it's burning right now so I haven't actually tested the DVD yet. The numbers or reference or location or what-have-you... in Mandriva was 1,0,0 and in Debian 0,0,0... unless I'm mistaken... It's actually the same computer, I have 3 Linux OSs and Windows on it... Is this normal? I mean, that it be 1,0,0 on Mandriva and 0,0,0 on Debian?

rm_-rf_windows · 06-28-2007, 09:50 PM

No, something went wrong this time round (on Debian). The DVD is readable on my Debian OS, but not on my FC6 laptop! I've had this problem before. Here's what I did:

Not quite sure why that may be! Could the warning messages provide us with a clue?
I'd like to understand why I'm having this problem, it would certainly satisfy my curiosity because I had the same problem when using K3b several weeks ago and I spent hours on it!

Many thanks.

Well, I've got things working now, however, I don't know what it was that I did that made it work, or perhaps it's just a hit and miss or a matter of luck. There's a little padlock on the iso file, I don't know why (on the desktop). I changed the permissions to 755 and ownership (user and group) to normal user. The little padlock was still on the icon afterwards...

I also modified the command and got no warning messages this time round:

When I have time, I'll have a look on the Mandriva iso to see if it also had that little padlock thing on its icon. What does that padlock mean, anyway?

To be continued...

The padlock is a sign of permissions.

The little padlock was still on the icon afterwards...

I also modified the command and got no warning messages this time round:
[code]debian:/home/linux/Desktop# cdrecord -dao dev=/dev/hdc speed=2 fs=64m -v -eject /home/linux/Desktop/SVG070629DOCS-X.iso

Thank you for the solution! I've been playing around with my kernel configuration for days trying to get my CD-R to work. Obviously I was looking in the wrong place. I tried the command you have above (substituting hdc with hdb), and it worked like a charm. I would imagine that using /dev/cdrom would also work. Anyhow, once again, thanks.
