Thank you for reply
If you boot to PE Builder or other disc and not into the Windows install on the hard drive, you should be able to defrag every file on the hard drive to maximum possible because no files on the hard drive are in use.
If I were able to find a defrag that is running from a boot CD instead of on the hard drive, I would get the best results.
Boot CD is supported in most bios chips but not all USB functions for USB 2 booting.
So I wish to boot CD and run a Defrag from there.
