My old SuperDrive DVR-103 died on me, so I got a replacement, DVR-104. It works beautifully. BUT! I remembered older SuperDrives needed firmware update in order to accomodate new x4 DVD-R media. So I checked out Apple site and found this. * For drives with the Product Identification DVR-104, no update is required if the Device Revision number is A227 or higher. * For drives with the Product Identification DVR-103, no update is required if the Device Revision number is 1.90 or higher. On my System Profiler, instead of showing anything starting with A***, it simply stated 1.10. So I figured the drive needs firmware update. But when I tried to install firmware update version 1.0 from Apple, it stopped in the middle of installation and said "no SuperDrive detected" or something like that. Now, question is, is this supposed to happen? Does this DVR-104 need firmware update? If so, how can I perform the firmware update? Please reply if you have any information on this.
