I've been getting a problem with one of my computers for a long time now. The problem is that I have a DVD drive that worked for a long time and now Windows only recognizes it as a plain CD drive. I also have a CD-RW drive that works as a CD-RW drive. I tried replacing the DVD drive with a second CD-RW drive that I knew worked and it only recognized it as a CD drive. I swapped the master drive from the CD-RW to the DVD but that didn't change anything. Anyone have any ideas why this is happening and how to fix it? Thanks!
