DVD RW drive won't read any blank cd after a burning proccess was intrupted.

My DVD RW drive has been working perfectly fine until recently. I was copying some audio files onto a blank cd yesterday, and the burning proccess was intruded because someone pulled the plug out of the computer. Now every time I put in a blank Cd in, the drive acts as if nothing was put in. It doesn't read the blank CD at all. Even Windows Media player doesn't recognize that there is a blank disc in the drive. I tried restarting the computer, but it don't help. It reads other disks perfectly fine, it's just the blank discs that don't work.

The computer is Vista Home Premium, in case that helps.

I'm kind of really new to this, and I'd aprreciate it if you took out some time to help me with this. If you need any other information, just ask,
