First, the old versions of the finder did not correctly calculate the
number of K free on a disk,  I don't remember the exact details, but I
believe it had to do with making 1K = 1000 bytes instead of 1024.
Second, the new finder has corrected this bug.  The 4K is probably from
the file, DeskTop, which is invisible.  The extra used space would be for
a directory map.

I haven't seen this happen.  Have you checked the information window to
show memory usage?   Some memory may be lost because it is being used by
the system heap.  Do you have the RAM cache turned on?  That would take
a healthy chunk away.   Hyperdrives will also cache 40K from you.
