how to extract iso from a CD/DVD

[vientito]

given a puppylinux disc sitting in drive, how do we extract the iso from it and burn on another blank? is there a utility to use?

This thread ought to give you what you need:

There are probably "guier" ways to do it too, but this works for me.

Puppy 2.10's Menu -> Multimedia -> WishCD CD writer has a "Copy data CD" button that may or may not make an exact copy. It only costs the price of a CD-R to try. Let us know if it works.

Be advised that the process requires enough memory somewhere (usually on a hard drive) for the program to temporarily store the contents of the disk you are copying. In the case of a fresh Puppy, that should be less than 100 MB. It may be more than that if you're cloning a customized puppy, but certainly not more than 700 MB.

to create an iso file from a cd or dvd, you can type:

cat /dev/cdrom > image.iso

or:

dd if=/dev/cdrom of=image.iso

if /dev/cdrom is not the name of your drive, use the correct name ... for example, my drive is /dev/hdc

or this might be more reliable:

type:

isoinfo -d -i /dev/cdrom

this should display information like this:
Logical block size is: 2048
Volume size is: 358979

use this information to type something like this:

dd if=/dev/cdrom of=image.iso bs=2048 count=358979 conv=notrunc,noerror

to burn the iso, you can use cdrecord, or the burniso2cd program in the Start, Multimedia menu ... or use whatever cd burning program you like
