Hello,

I have read suggestions of making multiple copies from an ISO file, or, if one has the CD and not the file, of installing Knoppix on the HD (compressed) and running it from there.

I have a CD-ROM and a CD-RW drive. I don't want to change my partitions - actually I want, but imagine the case I had a crash, or a small hard disk. Is there a way to make a backup copy of the CD?

On the fly copy works, but I assume it isn't a good idea to try to make an exact copy by reading from the device while Knoppix is running from the same device. Am I right?

But the files on the CD are still readable as files - or would this also confuse some programs or cause some overhead that will lock the system? Maybe it is possible to "construct" the CD on the fly? (I don't really know if this is possible.)

Another idea was to take or to make a minimal distribution (but which can read and write CD-R) that runs from the memory, but it would be nice if it all this could de made using only Knoppix.

It is just an idea. Maybe it isn't very important - for the moment, if my CD gets scratched, the simplest thing for me is to ask a friend or to buy a new one.

Bye,
Gencho
