Well, for one thing, you never have 305GB.  1024MB = 1GB.

You only had 298GB UNFORMATTED.  Formatted, you had 289GB.  With
8% reserve, you're down to 266GB.

Remember the 2MB floppies? 2,000,000 bytes = 1.907MB UNFORMATTED.
1.44 MB formatted.  Same principle applies to all disks.  Formatting
takes space, but makes the disk usable.
