Howto: Create ISO File From CD/DVD in Ubuntu Linux !

Have a CD or DVD lying around that you are sick of putting in the drive every time you need something on the disc?

How about just making an .iso file that you can mount as you need? Or maybe you just want a “master” copy of the media so you can create another copy at a future date.

At any rate it is rather easy to accomplish in Ubuntu:

sudo umount /dev/cdrom
dd if=/dev/cdrom of=file.iso bs=1024

You can also do the same with folders:

mkisofs -r -o file.iso /location_of_folder/

Don’t forget to make a checksum:

md5sum file.iso > file.iso.md5
