    I have two external drives I use. One as a primary, and one as a back up. I back up with Carbon Copy Cloner now (super duper was soooo slow) and it works like a charm.

    ...except when I right click and get info on both drives, they are different sizes (by 6GB), yet when I do list view and see the calculated sizes, they are the same!

    And yes, the trash is empty!

    It could just be different block sizes causing it to be calculated differently.

    You could try downloading OmniDiskSweeper, which is free, if you want an additional opinion on whether the size matches.
