Version 2.18.945 drive map erroneous display

Defraggler Defraggler Bug Reporting
1

Windows 7 Pro x64

Whenever I defrag my Seagate 1TB drive, the drive map starts displaying some data where there is blank space. It's freaking me out! I already checked my drive for errors, none found. My G: and S: are both using GPT instead of MBR but I don't see any weird stuff going on with C: or G: at all.

During quick defrag:

After:

Is this on my end? Problem with Defraggler? If I select individual fragmented files and defrag those then I don't see anything weird. Only when I quick/full defrag the whole drive.

You need to defragment the $MFT (Master File Table) for NTFS filesystem. Alas, Defraggler can't do this, because Windows defragmentation API doesn't allow this. You will need a third party util to do this. The bad news is that most of them are paid but I think there is some Perfectdisc free edition or some other utils that can do this.
