Linux Hard Drive Backup Problem

I bought a hard drive KARAOKE machine. It has a 1T hard drive with two pertitions. I like to back the whole drive up with another 1T hard drive. I tried Clonezilla (two different versions), both of them stoped with an error message (FS error...). I tried linux dd commend, it says access permision denied for source drive. I guess the source hard drive must be protected. Can anyone tell me how to clone it? Thanks. My linux version is latest ubuntu. I run dd from root.
