Just made a Knoppix CD for a neighbor. I put my Knoppix CD in
my burner (they are better readers than CDrom/DVDrom's).....
md5sum /dev/scd0 (to get the md5sum)
dd if=/dev/scd0 of=/home/tom/knop33.iso
....remove old CD and put a CDr blank in burner ....
biso knop33.iso (alias biso='cdrecord -v -eject
driveropts=burnfree speed=16 dev=0,0,0 -dao')
md5sum /dev/scd0 (get md5sum for new CD and compare to
previous md5sum above)
Since this new CD is for somebody else, and I was too lazy to
get the 'offical' md5sum from a Knoppix ftp site, I put it in my
DVDrom and booted it to make double sure it was OK. It was.
Of course the cdrecord options for 'biso' can vary, ie, -eject,
driveropts, speed, but -dao is _mandatory_ (to preserve the
md5sum, and should always be used for bootable iso's anyhow).
For d/l'd iso's all that's needed is to type 'biso <first few
letters of the iso name and hit Tab>', then Enter
My burner is a Plextor 52x CD-RW. CDr media used was 48x
capable, so I burned at 1/3 speed, 16x. IMO, never more than 1/2
speed of the lesser of burner/media ratings should be used, even
for data or audio CD's. 48x isn't three times as fast anyhow,
but can, and often will result in coasters. Cdrecord won't
normally use more than about 32x +, even if 48 and 52x media is
used, inspite of faster than 32x burners. YMMV, cdrecord
reports the media rating, requested, and then the actual burn
speed when finished.
....................................
To make an audio CD copy (same neighbor ;), I put an audio CD
in my DVDrom, and a CDr blank in my burner and type 'cpaudiocd'
alias cpaudiocd='ripacd && normall && bacd'
(which calls....)
alias ripacd='cdparanoia -vB 1- /home/tom/wav/'
alias normall='normalize -m /home/tom/wav/*'
alias bacd='cdrecord -v -eject driveropts=burnfree speed=24
dev=0,0,0 -pad -audio *.wav'
Due to batch normalizing the track volumes, the resulting CD
is often better than the original (specially commercial or
scratched CD's).
Just 'bacd' is needed to make an audio CD from wav's after
they're normalized with 'normall'. I like to use Xmms' disk
writer plugin to create the wav's from mp3's. If those mp3's are
from widely differing sources, I run normall twice. If there's
any doubt about the mp3's integrity, 'mp3_check' (Mdk contrib
rpm) will let you know about them. I like Xmms cause it displays
total time, and I can make sure I don't exceed 80 minutes. MB's
don't matter, they're often way over 700.
......................................
To make a data CD (including mp3's, .avi's, .mpg's, .mov's,
etc.), I select a directory containing the files I want to burn,
eg, ~/data In my home dir I type 'mkcdimg data/'
(alias mkcdimg='mkisofs -r -o cd_image')
....which creates a burnable image file named cd_image. Then
with a blank CDr in my burner I type 'bdcd cd_image'
(alias bdcd='cdrecord -v -eject
driveropts=burnfree speed=24 dev=0,0,0 -data')
Those two commands could be made into one alias, but I like
to 'du cd_image' to make sure it doesn't exceed the capacity of
the CDr (eg, 700MB) before burning. In no case would I endorse
trying to overburn.
All the above is the quickest, easiest, and most bulletproof
way of copying/burning CD's I've found. Just requires a little
one time preparation, ie, making the aliases in /etc/bashrc
'Sides all burning GUI's suck ;~>
