Make iso from cd or dvd rom with Ubuntu

to make iso just write this on your console:

sudo dd if=/dev/cdrom of=/home/mydir/Desktop/filename.iso

and to mount iso to you cdrom:

1) Create the directory aka mount point:

# sudo mkdir -p /mnt/disk

password: "your password"

2) Use mount command as follows (assumes that your ISO file name is disk1.iso):

#sudo mount -o loop disk1.iso /mnt/disk

3) Change directory to list it:

# cd /mnt/disk
# ls -l

then your iso will become files on your cdrom
