i'm pretty new to linux, so forgive my newbie lack of understanding. anyway, here we go:

i'm in charge of a web-server at work. i'm trying to create an easy system-revcovery method, in case stuff breaks and i'm unavailable. i have a plextor px-708a dvd+-rw drive, that's eventually going to be used for backup-purposes.

anyway, after looking around for a while, i decided that it'd be pretty easy to add a tarball and a short set of instructions containing all my important stuff onto a re-mastered knoppix boot disc.

as a first step, i tried to just burn the knoppix 3.4 image to a dvd+r, since that's the only kind of media i have on hand right now.
i messed around a lot:
-i tried using growisofs with the -Z flag, but it didn't like that at all:
Code:
# growisofs -Z /dev/scd0=/path/to/knoppix34.iso
:-( unable to open64("0,0,0=/path/to/image",O_RDONLY): No such file or directory
(which just is not true)

-i tried using cdrecord.prodvd, but couldn't get it to like the CDR_SECURITY key.... it always 'Alarm'ed out. so i eventually gave up.

every time i tried using cdrecord with the -doa flag, it complained about not being able to send the CUE sheet.
Code:
# cdrecord -v -eject -dao speed=1 dev=0,0,0 /path/to/knoppix34.iso
{normal-looking cdrecord stuff...}
cdrecord: WARNING: Data may not fit on current disk.
Starting to write CD/DVD at speed 62 in write mode for single session.

...
cdrecord: Cannot send CUE sheed.
cdrecord: fifo had 64 puts and 0 gets.
cdrecord: fifo was 0 times empty and 0 times full, min fill was 100%
anyone know what that means, or what i might be doing wrong?

anyway, that's beside the point. back to my problem. i ran it without the dao flag and it appeared to work fine. i couldn't mount the resulting cd... but i tried booting anyway, since i didn't know if i should be able to.

when i booted, i got the pretty knoppix boot-loader-esque screen. i hit enter and stuff started flashing... i got all excited.... then....

(hand copy, so there could be small mistakes)

i haven't been able to find any answers on the web or here. i know this isn't probably a knoppix-centric question, but i figured maybe somebody'd be able to help. is the fact that it won't mount telling, or is that expected behavior? am i using cdrecord wrong? do i have it set up incorrectly, perhaps? i'm going to try burning the drd+r using nero and windows from home and see what happens. but i'd be more than happy to take any suggestions you might have... as i need to get this stuff working eventually so i can automate these damn backups.

thanks in advance.
