Hi! I've the strangiest problem i've ever seen. I have a CD drive (attached through an udma interface) and a CD-RW (yamaha 8X8X24, attached through an IDE interface, my OS is XP Pro. the problem is that recently this two drives strarted, like read disc and burn (the burner) when there are NO discs at the drives at all. The worst part is that additionally they totally overload the system, could be for 10 sec, 30, a min. and sometimes the windows stucks at all (I can move the mouse, but that's all). Was anyone familiar with this problem before? Anyone who has the slightest idea please help. p.s. the Anti-Virus check resuled in clean system.
