Has my Firewire burner that can reanimate itself damaged CDs / DVDs yet, the iMac (Apple saves itself at the high prices dis they invented interfaces) by replacing the Firewire Bridge uncomplainingly into a USB burner can turn. Thanks to the integrated power supply no further "reconstruction" at the burner itself were needed. SATA Connector Connecting lead USB cable through the rear wall - done! Brenner is recognized spontaneously, all functions run without problems, the adapter has even in the housing space (as I do not otherwise need it for mobile use). So I can continue to stay current for little money with newer built-in burners. Good price / performance ratio! Fipsy
