On my BIOS, when I start the computer it says that I have a DVD-RW as master and a CD-R as a slave. But whenever I put a blank DVD in, the icon changes to CD-ROM. The CD-R works fine, it's just the DVD-RW that disappears.
I ever tried deleting the the upperfilter and lowerfilter in the registry, which caused me to repair my registry.
I have Win XP SP2 with all the updates, I just update NERO, I have 6.6.15a. My DVD-RW is a NEC 2500a, with firmware 1.09.
After 6 hours of messing with it, I'm at a lost at what it could be. Any help is welcomed.
