I work in Over the Phone IT and we've been using Diskkeeper 2009 on client machines for defragmentation purposes. I was just wondering if anyone can attest to it's effectiveness. Every time i run it the defrag completes in literally five to ten minutes. I used to let customers go after starting the defrag telling them it would take a while but i soon found that they would be calling back 5 minutes later saying it was finished.

It just seems like it finishes really fast to actually be completing a disk defragmentation.

I was just curious.
