I use Auslogic Disk Defrag mostly. I also use My Defrag. And I use Power Defrag, it is a GUI for Contig:

Contig
Whats new in version 3.0?
- Simplified Contig download and setup (now almost fully automatic)
- Removed PowerMode(TM) because of compatibility problems with Windows Vista
- Introduced TriplePass(TM) mode replacing obsolete PowerMode(TM)*
- Added ability to defragment removable drives (mostly floppy and USB hard drives**)
- Fixed few glitches
- New Vista style graphics
* TripleMode(TM) runs Contig in 3 passes defragmenting any remaining fragmented files
** don't use on USB flash and SSD drives as they are basically immune to the file fragmentation due to almost non existent access latency. Defragmenting flash devices also decreases their lifetime.
