Hello. I'm having the exact same problems that are being mentioned in this thread (i.e. ripping and burning has slowed down significantly, system resources at 100% when ripping adn burning, using XP, etc.). I'm looking forward to trying DMA solutions provided here.Can someone explain exactly what "defrag" is all about and why it's in my interests to do this often. (Note: Computer is about 2 months old and I've never done a defrag. Additionally, my drives are partioned. Do I need to do anything differently because of this?)Thanks,Scott
