    I bought a used mac and when I erase the disk, afterwards it still shows 2 files and 2 folders on the disk taking up 40+mb of space. What is that? When you erase the disk isn't it supposed to be completely empty?

    That's because the drive is formatted. Formatting takes up some space.

    yeah no HDD is going to be the full 250, 300, 500 or 1TB of space listed. Formatting reserves a small portion for the file system information and stuff. A 2GB USB drive is the same, it won't be 2GB, it will be 1.98 GB or something.
