Hi there, I've got two drives which i'm having problems with, one of them is a LiteOn IHAS124-19 Y. When I try to burn dual layer disks it keeps getting to 50% and coming up with an error and stops writing. I'm running the BLOX friwmare on it. I notice that there are liggy firmwares available but I don't know which one to use ie the orig or auto etc. Can anyone advise?
