I recently added a second DVD drive to my PC. The DVD-ROM is a GDR8161B. Secondary slave. The burner is the secondary master... Same as it's always been. About the time that I got the second drive, I put a BOATLOAD of data on my hard drive. I went from having about 300G free to having 50G free. When I rip a movie with DVDShrink, my mouse will randomly and sporadically freeze on me. Keyboard still works fine. Programs still seem to work fine except for a lack of mouse input. When I get my mouse back, mouse input returns, dumps any queue that I'd built up while it was locked up.... if I clidk anywhere, when the mouse finally unfreezes, all those clicks dump out and my computer goes nuts for a little while. I've defragged the machine. But I'm not sure that has anything to do with this because it happens even during the analyze... when data isn't being written to the HD. Both DVD drives are in UDMA mode, according to windows. Help?
