2008 Mac Pro burner failure - report "Sense Key = MEDIUM ERROR - Sense Code = 0x73, 0x03"
Problem just arose - burners working days ago - NO major changes in Mac Pro --- Attempting to burn some DVDs (data only), using the latest version of Toast v12.0 & Dragon Burn, as soon as I tell either my internal or external unit to burn, it runs a few minutes then pops up dialog box - "Sense Key = MEDIUM ERROR - Sense Code = 0x73, 0x03". Blanks are new Memorex. I've restarted Mac Pro multiple times, still no burning possible. In dire need to restore capability. Most gracious thanks for ANY immediate assistance.
Mac Pro, Mac OS X (10.6.8), URGENT RESOLUTION NEEDED - Thanks
