UltimateDefrag Freeware Edition
Full user review
"It'll ruin your hard drives faster but has a cool GUI."
This program has a cool GUI with a circle visualization of where data is on your physical disc.
This program WILL ruin your hard drive! I've used it on several computer multiple times and the hard drives always end up failing quicker! Stick to the default Microsoft Windows defrag tool. You can find this in All Progs>Accessories>System Tools.
