There's been alot on here about these drives, but nothing specific to what I'm experiencing. When I insert a blank dvd or cd it does not recognize it as anything being there. I've tried Imation 16X DVD+R, Verbatim 16X DVD+R, FujiFilm 16X DVD-R and +R, and Imation 1X-52X CD-R to no avail. I Fashed with the DRU-710A BYX4 firmware and still no dice. Not really sure what to try next. Could anyone help? Would be greatly appreiciated. Thanks in advance.
