how to create an iso image of a DVD?

guys,
I want a copy of an set of OE discs, but I don't have a DVD-rom in my laptop, my idea is mount those discs on an rx3600 box and create iso images, copy the iso files to my laptop and burn them to dvds otherwhere.
but i don't know how to accomplish it, could any one offer me some help?

regards
Stephen

Re: how to create an iso image of a DVD?

The cdrtools package includes a "readcd"
program which could do this. A Web search
for keywords like, say:
dvd image dd
should find many explanations of how to use
"dd" to do it.

> [...] and burn them to dvds otherwhere.

Why not just take the discs to the machine
with the DVD-writer, and do the copying
there?

Hey stephen,

Yes, dd should do it. Here is a small note on Viktor Balogh's blog....

An image of the DVD, yes. (Whether it's an
ISO 9660 image depends on what's on the DVD.)

My plan was for you to read this stuff, not
for me to read it and tell you what it says.

I already did this during a HPVM installation with a simple "dd" bs=2k - took some time, but works.

Hope this helps!

Torsten.

Re: how to create an iso image of a DVD?

It was VSOE that I tried to make iso image, and as I remember, dd should deal with raw device, so I dd 3rd DVD using dd if=/dev/rdsk/c3t0d0(DVD rom), bs 1024k,and at the end of the dd, it told i/o error, but I could still open the iso image, of course, unable to verify whether it was a exactly good image; I try block dsf on 3rd DVD, it finished without any error, and on 1st and 2nd DVD, saying i/o error again liked the 3rd DVD with character dsf.
Was there size limitation? look like I could only verity the iso image when I try to boot it as installation source.

Stephen
