Just found this discussion after a finding Defraggler to be *very* slow. It also hammers the processor, shown by the processor fan frequently kicking in at high speed and always running it at a moderate speed. Difficult to see how, once the analysis of the drive has been done, it can take all that power to issue read and write instructions.
As an indication of how slow it is, it took a whole morning to sort out a 206GB partition. On a 2TB drive it has run for 2 days and only got to 47%.
Makes me wonder just what it is acually doing!!??
