I own a Dell Dimension 3000. My CD drive is no longer being recognized. It still gets power and will open, but when I open Windows Explorer, all I see is my three hard drives, and my CD drive is not present. I have checked my IDE cable to make sure it is secured, as I have done with the other 4 prong cable (I don't know the name of this). Any ideas as to why this is happening? I hope I gave enough details, any help would be appreciated! I want to use my CDs again.
