  "Do not be alarmed. There is nothing wrong with your Desktop."

  What's going on is that ALL of the sectors on your disk are full, and that
622,367 bytes of that is being used for data. The rest of it is used for
"overhead", such as disk directories (and folders), FAT records (to keep
track of how a file is linked), and unused sectors. (In short, each sector
is allocated for 512 bytes. If you created a file that was only 10 bytes long,
you would have 502 bytes "wasted" because the sector is not completely full)
