burning data to cd-rw

southsibling · 08-11-2007, 03:12 PM

Seems too simple to need an explanation, but I just can't seem to get it. I want to copy my .vimrc file from my Home/Me directory onto a cd-rw to transport to another computer. Both are loaded with my Mandrakelinux 10.1 OS. (I can't do it on 'X', using Kb3, because that system doesn't recognize the 'hidden' files.)

On the command line, I've typed:

'cp .vimrc /mnt/cdrom

I get back:

cp: cannot create regular file `/mnt/cdrom/.vimrc': Read-only file system

What is it that I don't get?

"cp: cannot create regular file `/mnt/cdrom/.vimrc': Read-only file system"

You cannot write to a mounted cdrom file system. If you want to write to CD you have to write the entire file system to an unmounted CD. Use mkisofs to create the file system and use cdrecord to write the file system to CD-RW.

This is what I tried, and what I got for it:

[Sat Aug 11::lowell:~]:$ mkisofs VIMRCVIM.VRC|cdrecord dev=/mnt/cdrom
cdrecord: No tracks specified. Need at least one.
Usage: cdrecord [options] track1...trackn

Use cdrecord -help
to get a list of valid options.

Use cdrecord blank=help
to get a list of valid blanking options.

Use cdrecord dev=b,t,l driveropts=help -checkdrive
to get a list of drive specific options.

Use cdrecord dev=help
to get a list of possible SCSI transport specifiers.

Specifically, I made a copy of my .vimrc file that I called 'VIMRCVIM.VRC to agree with the 8x3 rule (all caps) and then invoked that filename with mkisofs and piped it thru 'cdrecord'

How far off the mark am I so far?

I used to have a script for burning files into a CD without having to mess with mkisofs and such.

Code:

#!/bin/sh

export CDR_DEVICE=/dev/hdc
export CDR_SPEED=52
export CDR_FIFOSIZE=51m

if [ $# -eq 0 ]
then
  echo -e "Use: `basename $0` [-s] <path to burn>\n"
  exit 1
fi

if [ "$1" = "-o" ]; then
  OVER="-overburn -dao"
  shift
fi

if [ "$1" = "-d" ]; then
  DUMMY="-dummy"
  shift
fi

[ "$1" != "-" ] && SIZE=`mkisofs -f -J -q -print-size "$@"`

echo Burning with device $CDR_DEVICE a ${CDR_SPEED}X

if [ "$SIZE" ] ; then
  mkisofs -quiet -f -J "$@" | cdrecord dev=/dev/hdc -tao speed=52 driveropts=burnfree -v $DUMMY $OVER tsize="$SIZE"s -
else
  cdrecord dev=/dev/hdc -tao speed=52 driveropts=burnfree -v -
fi

exit 0

Please change all the devices according to your specs.

Script done by Javi Polo (I'm merely pasting it here)

With this script, you just type "burn <file(s) to burn>" and you're ready to go (assuming you named burn that little script)

Unhide the file by removing the '.' before the file, burn in K3b and then rename again at the destination computer.

Perhaps you sensed-at this end-a big "Duh!" when you offered your solution?! Perfection...is really the application of elegant simplicity, isn't it?*

You get the prize for this one!

Thanks to all for the help. I did manage, at least, to successfully create a '.iso' file; haven't been able to burn it to CD yet, but I'm gonna keep plugging away at that one. Lotta new stuff learned here.

*(Oh, yea. I spent probably, ohhh, 30 seconds putting the whole thing together, including loading it onto the other computer and 'sourcing' it.)
