66880 KB is the capacity reserved for the superuser. The percentage of the reserved capacity can be set when using the newfs -mcommand.

Capacity Manager calculated the total capacity by using the equation discussed previously (used capacity + available capacity) and displayed the result in megabytes:

1904031 KB + 4717165 KB = 6621196 KB

where

1904031 KB is the used capacity

4717165 KB is the available capacity

Because Capacity Manager does not include the reserved capacity in its calculations, the difference between the two calculations is the capacity reserved for the superuser, which is 66880 KB.
