How to create ISO CD images?

What is the program used to create ISO CD images? i.e. if you wanted to write files to a CD-R or create an image of an existing CD?

thanks,

T

mkisofs is used for making iso images. CDRtools contains the apps that are basically always used. You will see a lot of programs like Arson, ERoaster, GCombust, and XCDRoast, but all of them are front ends to the CDRTools package.

I haven't used the front ends much.. I've only burned a couple cd's since I started playing with them,lol. CDBakeoven looks like a very good one, Arson seemed good for what little I used it, and I can remember XCDRoast had been okay when I used it on slackware but it doesn't seem to play nicely with gentoo's cdr setup very well (it wants to have the permissions changed for its "non-root mode"...) and it seems to lack behind anyways.

Some of the front ends do iso, some do audio, and some (most) do both. I recommend playing around with the packages in app-cdr and see what you like.

from the command line it is

make the image
mkisofs -r -o cd_image directory/
check it works
mount -t iso9660 -o loop cd_image mntpt/
check find your cds scsi point (although you can do this with ide and newer versions of cdrecord there is a thread under documentation tips and tricks about this)
cdrecord -scanbus
test burn (dev=0,0,0 are from cdrecord --scanbus)
cdrecord -eject -dummy -vvvv speed=8 dev=0,0,0 -data cd_image
brun
cdrecord -eject -vvvv speed=8 dev=0,0,0 -data cd_image
mount the disk to see it works
mount -r -t iso9660 /dev/hdc /mnt/cdrom/

This didn't work too well for me:

Code: Select all

$ mkisofs -r -o image.iso /mnt/cdrom

File names were truncated to 8.3. But

Code: Select all

$ dd if=/dev/cdroms/cdrom0 of=/tmp/image.iso

Seemed to work better. ( Make sure your cdrom isn't mounted first!)

isnt that only useful for making an iso of a cdrom? it is already in iso format on the cd anyway. would that work for a directory? say for example my home directory.?

Hello Gents,

If you have KDE installed, merge an excellent graphical user interface tool called k3b. Spend the next 3 minutes setting it up as root. Click on 'tools' and then click on 'write ISO image...'. That's it.

Regards,

Mystilleef

You're 100% correct - it's only useful for creating an iso image from an already existing CD - which was one of the original questions.

do 'dd if=/dev/cdrom of=cdrom.iso' make a dao image?

Try it. You can test the image is good with

Code: Select all

 $ mkdir testMount; mount -t iso9660 -o loop ./cdrom.iso ./testMount

Then look in testMount directory - it should look just like your original cdrom.

[edit]I don't actually know how to create a dao image, or indeed what a "Disk at Once" image is. This technique will simply create a copy of an existing cdrom, which can be burnt in a single session.[/edit]

I think dd's output iso's are dao-compatible. I always use dd to create disc images, and they burn just fine using dao mode in eroaster/cdrecord.

If you want an iso image of a cdrom, you can do that :

cat /dev/cdrom > image.iso

(your cd must be mounted)

unmounted or mounted, it will work. (dd or cat)

Code: Select all

cat /dev/cdroms/cdrom0 > cd.img  # The UNIX way to do it
dd if=/dev/cdroms/cdrom0 of=cd.img bs=4k # More control & efficiency
mkisofs -J -o image.iso /mnt/cdrom # compatible with Windows, MacOS, Mac OS X etc.
mkisofs -R -o image.iso /mnt/cdrom # compatible with various *NIX and UNIX
# I have no idea what the difference between -R and -r is, other than that '-r' is more 'rationalized'

when specifing path like /opt/disc1 /opt/disc2 it writes not directories themselfs, but brings files from them in to the root of the image. is the one only possible way to do it with -graft-points and manual specification hwo it must be on image (e.g. disc1=/opt/dsic1 disc2=/opt/disc2) ? pretty much typing
