Optiarc ad-5240s advice required

Hi there, I’ve got two drives which i’m having problems with, one of them is an optiarc ad-5240s. 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 1.03 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? and if i update will it solve the problem?


If you have the same issue with two different drives, the most probable cause is the disc.

Too bad, only Verbatim proved to make reliable dual layer discs.

What discs are you using? What burning speed?
