I'm in the process of building a new computer but my old computer is having some major CD-ROM problems. The system is shy of 3 years old. I had my first Mitsumi 6X CD-ROM replaced about a year after I bought the system. It was replaced under warrenty because it was defective. It would take a LONG time (nearly a minute) to access the drive and would hum and rattle VERY loud then stop dead and repeat. They replaced it with a newer 8X Mitsumi CD-ROM. Hear I am a year and a half later and the problems are similar but MUCH worse. Same symptoms as above plus it many times will never access the drive. I may have the CD drive disappear altogether or upon access to the drive it will reboot my system. Is this typical of Mitsumi drives? Seems suspicious that it happened twice about 1 year after installation. They both worked fine when they were first installed. Are their drives 1 year disposable drives?

Thanks for any help!
