Can't read with GH20NS15

I have a GH20NS15 I bought last year, I can’t seem to be able to read from it, but it still burns discs.

I’ve tried it with a retail disc, but can’t read it.

It burns and verifies fine. I’ve tried discs I’ve burned with this drive on my other comp…works fine.

What’s the problem?

The problem is with some crapped software/driver installed.

If a drive can burn, then it also can read.

Is Alcohol, daemon Tools, incd or similar installed?
