I have a Sony DRU720A DVD writer. After I upgraded the firmware from JY03 to JY08 my drive cannot recognize DVD+-R. It can recognize DVD-ROM, DVD-RW and CD's (CDR).
The problem is not with the media and the drive was reading/writing DVD+- R prior to the firmware upgrade.
Nero Info tool shows "no disc inserted" even when a DVD+R or DVD-R with data is inserted in the drive.I get a power calibration error when I try to burn DVD's.
My DMA settings are fine (unchanged).
Can anyone help?
Sys Config: Windows XP Pro, 2 Ghz Celeron, 512 MB RAM, Burning Software: Nero 7
