My dvd burner will not recognize a blank dvd-r. I am using imgburn and i get the error "Device not ready: ID CRC or ECC error". The disc is a Taiyo Yuden dvd-r. I was able to burn a Verbatim dvd+r but not the TY dvd-r. My burner is a MATSHITA DVD-RAM UJ875AS and my laptop is a Lenovo Y450 running windows 7. I have also tried the same TY disc in another laptop and it was recognized perfectly. Any help on this would be great.
