Man this sucks.

My A drive keeps spitting out disks. Even if it takes it, it'll make a high pitch whirring noise. Any idea on what happened?

Did you get something stuck in it?
Even small fragments can mess up the drive.

is this an external or internal

Internal. It's still rejecting disks and making that noise.

make sure there is nothing in the drive like the little metal part. If you can try to blow some canned air in there, because it sounds like a hardware problem.
