I've just installed defraggler v2.07.346(x64). The analysis says no fragmentation at all, and all the blocks in the map are blue. However, when I hover over them it says "no files in the block". The amount used and free on the drive seems to be correct. I have scanned with other defrag programs which seem to detect fragmentation of 10% approx.
Reinstallation does not seem to help, and I'm having the same problem with my portable version. I'm running win 7 SP1 x64 home premium.
I have had something similar recently happen to me while showing a friend the benefits of Defraggler.
But it was slightly different for me. In this case, it showed files in the top area as fragmented, & lower down, it showed a line of blue blocks, where would exist 0 files when you hover your mouse over the blocks.
So, it defragged the fragmented sections, I think, and it still had these 0 files blocks that were blue near the bottom.
I mean, the files on the top were defragged, & there was a band of white free space, then below that, a line that showed nothing but 0 files blue blocks.
I believe this was on a 32 bit 7 machine with 2.07 of Defraggler
