There's no problem with your disk. The two different figures come from
the fact that a file being saved on a disk has space assigned to it in
standard sized chunks but it may not use all of the space it has allocated
to it. Take a look at the "Get info" box for a file and you'll see the
two different figures for an individual file listed right there -- the
size of the file and the space used by the file on the disk. When you do
the multiplication to account for the fact that the units of measurement are
different, the sizes are not exactly the same.
