Disk defragmentation

For me, who have left a part of his heart with XP, Vista defragmentation tool is a sore disappointment. There are may be some clever algorithms behind the scene, but I feel insecure, staring at incomprehensible message "Defragmentation is running. It may take minutes or hours...". Bill's balls! Why these guys slumming me with so much of unwanted graphics, would cut off the actually useful one?!

These are third-party alternatives I found:

1. PageDefrag from Sysinternals. The name is the best recommendation.

2. Auslogic Disk Defrag seems to have good reviews.
