Not a problem.
When I run your snippet i get:
>ruby -w fwrite-test.rb

It looks like seeking on an empty file fills it with null data.  Not
sure if thats a Ruby thing or a feature of the underlying IO libs.

change the 'w' to an 'a' (an delete the current 'junk' file)
and the file produced looks like:
012345678
012345678
012345678
012345678
012345678
012345678
012345678
012345678
012345678
012345678
