All of a sudden my dvd-rom cannot read dvd's and cd's. I have a Sony Vaio PCV-RS620G Desktop running Windows XP. I also have a DVD+-RW/CD-RW drive (HL-DT-ST DVD-RW GWA-4082B) that works fine....

I might be confusing the names of each drive but the one that cannot work is the bottom disk drive (which says DVD-ROM).

I tried using firmware but that won't work for some reason...it says wrong drive or something.

Thanks.
