Just to add this to people's choice of what they use to defrag, released today.
Have a read, the download is at the bottom of the page
Oooo, looks interesting. I'm gonna give it a try.
That's a nice find Hazel, but I must confess to not knowing enough about HD structure to know which is the best way to lay down files for optimum performance.
Different Defrag programs give different suggestions regarding this, and I've read the great defrag shootout, but I'm still left scratching my head. 
This is still one to download and keep however. Thanks.
Looks alright. I'll give it a try after I have my virus BHO mess cleaned up.
