So my combo DVD/CD-RW drive worked fine until just recently. Then all of a sudden it started having problems with writing CDs, but for some reason restarting at least once between each CD seemed to fix the problem. Now however, it won't even recognize DVDs. I have tried several different movies as well as burnt discs and every time it says that there is no disc in the drive and pops it out. I have reformatted the hard drive, uninstalled the drive while in safe mode, and even re-flashed the firmware so I am pretty confident that this is a hardware issue. Is there anything I can do short of buying a new drive? If I have to, where would I find it and for how much?

Thanks!
