I noticed this when I was burning a CD (with Nero) yesterday, which is the first time I've burnt a CD with my new GA-7N400Pro board. The CD burning process was taking longer than it used to and I also noticed the floppy drive light would turn on often even though there was no disk in the drive. The floppy was acting like this once when I accidentally disabled ATA in the BIOS. The floppy would try to read whenever my harddrives would be read from (very annoying). However, simply adjusting the BIOS fixed that. According to device manager, there are no conflicts with the floppy or harddrive controllers. The Primary and Secondary controllers show the appropriate DMA settings. It just seems like the floppy is interfering with the CD channels. BTW: My CDRW is master and the DVD is slave on the secondary IDE channel. I have 2 harddrives on the Primary IDE channel. Any ideas?
