I recently purchased a 1655 and I’m starting to wonder if I was sent a reburbished/returned item. It wouldn’t really bother me much, but about 60% of my burns are failing. Sometimes the burn just hangs there. I’m using Verbatim DL discs from two batches, so I don’t think it’s the discs. I’m burning with ImgBurn.
I was first suspicious of receiving a refurbished/returned item when I noticed the jumper cable was set to slave. Is that normal? Isn’t it usually on master?
