I bought a Samsung 320 GB external Hdd and I formated it NTFS.

The hdd is connected via usb.
I put some files on it and when I try to defrag it with defraggler I get the message that Analysis Failed.
I made a truecrypt volume on this hdd and after I mount it I can defrag it with Defraggler.
What is the problem?
