I just bought a brand new BenQ 1650 and an external usb enclosure. I put the drive in the enclosure connected the power and data cables with the jumper on master and connected it with my laptop. It was recognized and all, but when i attempt to burn (or even read) a cd/dvd, it takes a long time to open it and sometimes even freezes… I was wondering if this is a problem with the enclosure or the drive. I don’t have a desktop so i can’t try it on that. I would like to know if the drive is faulty before i return it. Any help would be appreciated.
