SuperDrive Problem

Hey Everyone,
Today I went and reset the DMA on my drive so the read speeds would be faster. After I did this, the drive stopped working all together. First I put in a DVD, it made awful grinding noises so I ejected it. Then I tried a different CD and the drive took the CD, but it wouldn't spin up. It just made a strange like beep noise, err-eee-errr and it wouldn't read. So I am guessing my SuperDrive is toast? Is this something that I done?

Also, I am out of AppleCare, I didn't opt for the extra warranty because I've never had to use it in my life. However, of course, I would now. Is there anything that can be done about this?

Or will I just have to buy an external drive for my movie watching needs!

Anyone else experience this type of issue and know a fix?
Thanks everyone.

 

Any ideas anyone?
...
It's been a month and it still isn't working. I was wondering if I should open my computer and take a look myself?
Thanks for any help.
