[qanda]This thread is about the Sony DRU-510A. Click here to see full specs[/qanda]I have the two burners listed in the title above. They seem to be operating just fine even though they may be considered quite old now. The only problem that I had that was associated with the burners was that they errored more using DVD-R discs. I have since converted DVD+R's and have not not experienced any failures that I thought were burner related. I do get read errors on certaind DVD's that I backup using DVD Fab. Could the age and technology of the burners effect making backups of current material out there now? I think I have the last firmware that Sony provided for these burners but that was at least 2-3 years ago.
