I have a Pioneer DVD-RW DVR-K15 burner in a Sony Vaio Laptop. I just discovered that it will not erase any RW media I have. I tried both a Memorex CD-RW and a Sony DVD-RW on Nero and Alcohol 120% and everytime it said that it was not a RW media.
I know it is not the discs because I took both to my desktop and used nero to successfully erase them.
Any insight would be appreciated.
