1GB = 1,000,000,000 bytes. 1TB =
1,000,000,000,000 bytes. Once formatted, the actual avail-
able storage capacity varies depending on operating environ-
ment (typically 10-15% less). For example, if the total disk size
is 500 GB, the formatted capacity should be approximately
465 GB. If the used capacity is 145 GB, remaining capacity
will be 320 GB.
