[opensuse] Cannot burn DVDs from the command line

10 Aug 2007

      Hello,

I have just been put in front of a computer with Suse 10.1 x86_64, a  NEC ND-4550 DVD burner on /dev/hdc and a few DVD-R disks. I need to copy some critical files to those dvds as soon as possible, as I have the feeling the drive is failing and, for some reasons I haven't investigated yet, X won't start. Nice, uh? :-(

I have tried:

growisofs -Z /dev/hdc=/dev/zero                    to blank it
and then the command at the end of this mail, pasted with its whole output.

What am I doing wrong, or missing? SI have checked, and that burner does support dvd-r. Surely something very stupid,
being tired as I am these days, but I really need to backup those
files out of that hard drive as soon as possible before the computer
dies on me or I can investigate if its problems can be fixed.

Normally I still use CDs, that's why I am unfamiliar with DVD quirks,
but the files this time are too many and too big to go with CDs.

And no, unfortunately there is no other way to backup those files (no other computer to which I could connect it, no broadband or enough
online space to upload the files somewhere...)

I have already tried to look up those error messages via google, but
frankly haven't recognized anything useful.

So please help me to walk through this: what is the exact, foolproof way to burn the whole content of a directory from the command line, from unwrapping the dvd from the case to removing it from the burner? what are the exact command to type, and in which sequence?

Thank you a lot, guys,
Ando
