I searched on this problem and it seems that a few users are having issues with the damn thing not working or burning slowly.
Please share your experience with this drive. I’m especially looking for information on whether your drive can consistently provide rated speed and which media works with this drive.
My DRU-530U has a 2.0c RPC1 firmware currently and while it burns Sony branded DVD+RW at 4x(identifies as Ricoh in DVDInfo), but I realized it won’t burn at 4x on 4x hp media(identifies as CMC in DVDInfo).
Nero allows me to select it, but when I start burning, it’s only half way done when estimated time goes to zero, so I’m guessing the driver is internally switching over to 2x/2.4x :a
