if your external harddrive is larger than your internal i would use

sudo ddrescue /dev/sda /dev/sdb logfile

note: sda is your source disk sdb is your destination drive (external).
this will also overwrite any data on your external drive

you can install ddrescue via sudo apt-get install ddrescue

i prefer ddrescue over normal dd becasue it gives you a nice progress bar and it will log i/o errors
