I have a sony optiarc ad-5280s that burns perfect xgd3 games and is connected via sata to usb and when I open up imgburn and put in the disc my drive disconnects and takes 15 seconds to reconnect. I also tried burning destiny at 4x speed and it came up with an error saying the semaphore period has expired or something like that and stopped burning. I would really appreciate it if someone could help me out by telling me a solution to this and please don't say get another drive or an xk3y.
