Unfortunately, I can't use any beta version here, but I?ll double check in other lab and I?ll let you know.
Anyway, if this is a OS mismatch of free space computation, I don?t think Defreggler change any code in order to try to fix this...
Any helpfully message about this "differences" should be good to see in the screen design of Defraggler. Showing more than 100% of fragmented space is not a good number to have idea of fragmentation status.
