Convert CD/DVD ROM to ISO file in Linux

Disc is easy to lose data if taking physical damages
If the disc is store with data files independently, just copy the files to the harddisk to backup the data
However, if the disc is an install disc, although the files are copied, some of them cannot be functioned
If back up a disc with an ISO file, we can write a disc on any time with any disc writer

Insert and load the disc

Open Terminal and type
ls -l /dev/*rom
check out which CD/DVD ROM is using

dd if=/dev/<your CD/DVD ROM> of=<output file>
if the path of if or of including space(s), the string of path must use ' or "
