I have a Sony DVD RW DRU-530 A drive, it will read data or play music or movies & I used to be able to drag & drop or "send to" files to be saved, now if i put a blank disk in the drive & try to save to it I get a notice to put a writeable disk in the drive I also have a Matshita DVD-Rom SR-8586 drive on the computer & I get the same notice if I try to use it. I have installed & reinstalled Roxio 7 & that made no diffrence. Checking both drives in system-Properties it says both drives are working properly--Thank You--Roy
