Until recently I could copy an audio CD in just over 3 mins with Nero 5.5 using my 52x creative CD ROM and 24x Teac writer under Win XP pro. Recently however, it has been taking over 8 minutes. After about 30% of the disc has been copied, the read buffer falls from its usual 90%+ to 49% and stays there, also the device buffer drops to 6 or 7% full. Both drives have DMA enabled. CPU is AMD 2400+ Any ideas?
