[qanda]This thread is about the Sony NEC Optiarc 20x S-ATA DVD Multi Writer Black. Click here to see full specs[/qanda]I consistently get this drive hangs up when attempting to burn. It seems to finish and then just sits there and never finishes. (spinning beach ball). Is there a patch or a firmware update that I am missing?
