A resource fork that contains no resources still contains the resource map
and header.  So the resource fork won't be completely empty.

The reason is takes 3K of disk space is that disk space is allocated to
files in chunks.  The chunk size is set when the volume is formatted.  A
small chunk size means there are more chunks to keep track of (there's
probably some absolute limit on the number of chunks); a large chunk size
means that some disk space is wasted.

To delete the resource fork entirely you probably need a special utility.
MPW's duplicate command, for example, can be used to duplicate only the data
fork.  --
