defrag tool

can anyone recomend a good defrag tool. i look at the ones available here but not sure what one to try. thanks in advanced....

 

Perfect Disk 8.0
30 day free trial
Works with as little as 5% free space

Downloaded it last night, best I've tried,
after 30 days back to jkdefrag

 

Diskeeper is the best ive used but its commercial

 

Same here, tried everything, nothing to match the 07 version of Diskeeper. well worth the money, can really forget abt defrag once you install it. Works intelligently on task priority basis. Not once have i had crashes or hangs unlike my experience with other defraggers.

 

I use O&O Defrag 10,and boy is that good software.I don't even think about replace him. Just hit One defrag button ,setup few parameters,click finish,and forget about defragment files.Even have boot defrag.Every one here can say that O&O defrag10 is the best defrag software in the world.

 

I use Power Defrag GUI, freeware available at MajorGeeks downloads.
