Thanks.
I fixed this bug a slightly different way

-               blocks = ochunk/512 * nchunk/512 * odata * ndata / a;
+               blocks = (ochunk/512) * (nchunk/512) * odata * ndata / a;


See

Those static numbers always make my nose wrinkle.
Don't we have the blocksize somewhere already? I'm also concerned what  
happens when true 4k sectors are used..
