DVD drive not recognizing my CD's or DVD's?

Question

I have Windows 7, and in the last day or two the DVD drive won't open my DVD's or CD's.  A green bar moves slowly across the top of the screen on the G  RW Drive icon in My Computer, as if it is trying to read it, but it never opens it.  When I click on properties, it says the device, a MATSHITA DVD+RW UJ8C1 ATA is working properly.

My question is that there appears now to be another device, listed as ST9750420AS ATA device, listed as a disk drive.  I'm not sure where that came from or what it is, and I'm wondering if it is causing a conflict or if it is actual software that came with the computer.  Why do I need a second device there?  Apparently, this is also working properly, but I don't want to uninstall it without knowing why it is there.  Any ideas or suggestions would be helpful.

I have tried disabling and even uninstalling the first device (the Matshita) and rebooted, also updated all the necessary drivers.  Can I just uninstall the second device?  Is that what is causing the problem?

Thaks in advance...

I strongly advise against uninstalling the ST9750420AS ATA device.  That's a Seagate Momentus 750GB internal hard drive, which probably runs your operating system.

I'd be interested in hearing what others would say about replacing the DVD drive.  They're only $20-$30 each.  If you go to Craigslist, Freecycle.org, or your local thrift store, maybe you can find a DVD-RW cheaper (or free).  Maybe find a free computer, yank out the old drive, install it in your computer, and recycle or donate the rest of the computer.  Meanwhile, try the disks in another drive to make sure they work.  (They probably do, but I thought I'd mention this just in case.)
