I'm writing simultaneously to dual superdives on a MacPro (Snow Leopard). One burn in 3-4 burns I am getting this error in two pop-ups, usually from the lower drive. One DVD copy will be okay but the other will not.
Sense Key = ILLEGAL REQUEST
Sense Code = 0x21, 0x02
I'm using Verbatim DVD+R single layer. Anyone have any ideas? I would be very grateful.
