When I built my comp, it came with an Optiarc DVD burner.
It was DOA.
Contacted Optiarc and told me to run this test - Opti Drive Control website
It showed failed and they sent me another one.
That one died after about a week.
I threw it away and will NEVER
buy another one.
You can run the test, and if it is under warranty, get an RMA, and sell it.
