copying knoppix cd

**sschardi** · 03-08-2003, 06:21 AM

I have been trying to copy the knoppix CD I got from Cheap Bytes.
I have tried making an image, doing a direct data copy, using blindwrite,
nero, etc. most are coasters, 1 will try to boot, but can't. How do I make
a bootable copy from a bootable copy???

Salve sschardi!

see CD-Writing-HowTo and use CDRWs

4.7 Is it possible to make a 1:1 copy of a data CD?

Yes. But you should be aware of the fact that any errors while reading
the original (due to dust or scratches) will result in a defective
copy. Please note that both methods will fail on audio CDs! You have
to use cdrdao or cdda2wav on audio CDs.

First case: you have a CD-writer and a separate CD-ROM drive. By
issuing the command

cdrecord -v dev=0,6,0 speed=2 -isosize /dev/scd0

you read the data stream from the CD-ROM drive attached as /dev/scd0
and write it directly to the CD-writer.

Second case: you don't have a separate CD-ROM drive. In this case you
have to use the CD-writer to read out the CD-ROM first:

dd if=/dev/scd0 of=cdimage

This command reads the content of the CD-ROM from the device /dev/scd0
and writes it into the file "cdimage". The contents of this file are
equivalent to what mkisofs produces, so you can proceed as described
earlier in this document (which is to take the file cdimage as input
for cdrecord). If you want to see a progress-meter and other fancy
stuff, then you can also use Jörg Schillings sdd.

In case you run into errors, then install a recent version of
cdrecord, which ships a tool called "readcd" (found under misc/). It
gives you the same result as dd, but reads sectors on the CD-ROM
several times in case of errors.

Thanks, but as a newbie, this could take me awhie to fugure out.
Is there any way in Windows either 98, 2000 or xp to make the copy of
of the knoppixx cd so the copy will bootable? Can I take the linux boot floppy, and use that to make a bootable cd in Nero, and then move the
file folders from Knoppixx to the new CD?

Good to remind this - I forgot to warn you usining cdrecord
without knowing what your doing. If you have SCSI hds, too,
cdrecord can demage your datas from a whole hd, when you
use the wrong options dev=0,0,0 (controler,id,partition)
To find the right device, use "cdrecord -scanbus" first:

root@0[Desktop]# cdrecord -scanbus
Cdrecord 1.11a34 (i686-pc-linux-gnu) Copyright (C) 1995-2002 Jörg Schilling
Linux sg driver version: 3.1.24
Using libscg version 'schily-0.6'

Excuse me, when I have no clue how to copy a CD with Windows.
Hope that a M$-user will help you soon.

PS: Your question is a good one for the FAQ

with nero or alcoholic 120%, there is no secret.
A simple cd copy. Cd to CD. Dont burn "on the fly", may be your problem here. Let nero copy the cd to hard disk first.

Also, you may use winiso to make an *.iso image of the cd.
Then use nero, alcoholic 120% or similar tool to burn the *.iso

</snip>

ALL CD-burning software can make an "image" from a CD, a snapshot, if you will, of the contents. The standard image format is ISO, but if you rip the image and burn from the same software, using the internal format is OK; for example, PrimoCD/Click'n'Burn/RecordNow uses a .GI ("global image") format by default -- but can also use ISO files.

DON'T copy CD-to-CD. ALWAYS rip the image first, then burn from the image. This will ensure the most reliable burning -- even if the drive has buffer-underrun protection (BURN-proof, JustLink etc.), data interruptions produce small gaps in the data that can cause glitches and potential errors.

A side note: under Windows, make SURE that DMA is turned on for your CD drives. It really makes a difference in performance, and it's not always turned on by default.

Thanks, I have tride Alcohol 120%, but when booting with copied CD I get lots of loading errors. Knoppix never gets booted. I thought it was my computer, as I have GoBack on it, but I get the errors on every computer.
I have enough coasters now to host a poker party

Finally, used WINISO and followed the directions on bootableCD, and then burned using Alcohol 120. Now good bootable copy.
Knoppix is very good distro to learn on without having to modify my main PC. Works good on my notebook also. Thanks for all the
responses.

Salve!
>using Alcohol 120. Now good bootable copy.
And I thought this was a joke or a new drug, alcohol 120%...

>Knoppix is very good distro to learn on without having to modify my >main PC.
Thants an important point. GNU/Linux is much more than having KDE
with nice programs running. But where to start to learn?
Best way is to visit a friend and asked him to show you some basics,
or to read linux newsgroups and ask question, or to read
Linux - tutorials like the rute book:
http://www.icon.co.za/~psheer/rute-home.html
Unhappyly not under GPL

but good.

>Thanks for all the responses.
Your wellcome, have fun & help later your friends or others
