I've used O&O 2000 v3.5.562 for several years from 2000 to XP. It's a champ! They had a pay version 4 that allowed boot time and MFT defragging among many other features, that was great too. They stopped offering the free version and their newest pay version has some very questionable big-brother, over-the-shoulder practices.
The old free version 3.5.562 is available
here ...scroll down to the sixth one on the list. I highly recommend it.
