    Yes, you can do that.

    Use the option to Securely Erase Free is as close as you can come. It securely erases all the space on the drive not occupied by an extant file. However, it does not erase your Home folder nor any other part of the drive that's in use.

    There are some (not many, but some) models of external drives that come in enclosures that are not capable of booting Mac computers. The drive can boot the Mac when used as an internal drive, but certain enclosures have firmware that is not compatible with Mac OS booting. What was the model/make of the external drive? Make sure the one you purchase for cloning to is capable of booting the Mac.


    If you look at the online Discussions for SuperDuper and Carbon Copy Cloner you will find lists of exernal hard drives that seem to not be capable of booting Macs.
