Hi, I'm new to these forums and I have recently been having some problems with my LiteOn SOHW-812S DVD burner and I was hoping that someone here could help me. My drive worked fine before then one day I tried to burn a dvd and it would not read. I upgraded to the latest firmware, US0Q, and I put a dvd movie into the drive. A green light repeatedly flashes, then the drive beeps and the process repeats itself. I have tried re-formatting my computer, and I have ensured that the drive is a master and that it is in DMA mode. I could really use some help.
