Hi Gang: I've had this problem since since I bought CD-rom. I've got a Lite-on CD-RW, I also have a kenwood True-x 52x CD-rom. The CD-RW is master (1st on the cable) and the ROM is 2nd. My problem is sometimes MSExplore doesn't see the CD-ROM drive and I can't make them switchable in the sense that a graphics or game program using the CD-RW as a read ROM one time won't pick up the CD if I load it in the CD-ROM the next time. Also sometimes running the CD-ROM slows my system down to nada. screen freeze the whole 9yards and I gotta reboot to get out. I've tried to switch Master/Slave and the CD-RW behaved as the ROM did as Slave. any suggestions?
