Talk:Making an ISO from CDROM

I usually use: dd if=/dev/hdc of=cdrom.iso bs=2048

And nothing more. It keeps the ISO from going beyond the actual size of the compiled data on the disc. I also think it is better to use /dev/hdc because it is DVD/CD-ROM neutral. On ubuntu, I believe /dev/sdc would probably be it, but I'm on Gentoo.

I think this should be merged with the other dd article. --Tatsh 09:40, April 28, 2008 (EDT)

Better yet, include the ISO size in the dd command: dd if=/dev/cdrom of=cdrom.iso bs=2048 count=`isosize -d 2048 /dev/cdrom`

Otherwise your .iso file may be larger than the capacity of the CDROM.
