While the Partition map type of the Hitachi is: GPT (GUID Partition Table)įinally, thank you for a wonderful backup tool. In comparing the two profiles of these drive, I note that the Partition map type of the Maxtor that is not seen as "bootable" is: MBR (Master Boot Record). Partition Map Type: GPT (GUID Partition Table)Īny ideas on why the external USB connected Hitachi is bootable and the external USB connected Maxtor OneTouch is not bootable? Vendor ID:Đx152d (JMicron Technology Corp.) Here is the info from Profiler from the Hitachi: If I unplug the Maxtor, using the SAME USB CABLE and plug in my external Hitachi, it spins up, mounts and is recognizable with Startup Disk. Partition Map Type: MBR (Master Boot Record) Still I cannot see the Maxtor OneTouch as bootable. This took less than 10 minutes and I verified in the Log that the disk was set to be bootable. So I tried then to recopy the data, but this time using Smart Update. Unfortunately, when this finished, this Maxtor OneTouch was NOT recognized as a valid Bootable disk using System Prefs -> Startup Disk. I formatted Mac OS Extended Journaled, and let SuperDuper! have it's next two hours doing the initially Erase, Copy all and make bootable. This is also a 320GB disk, and with the same USB 2.0 to USBmini connector. Now, today I was in Sam's and found a real deal on a Maxtor OneTouch 4 Mini. Since I don't know the magic key code to select an alternative boot volume on power up, I use System Preferences -> Startup Disk and the external disk is recognized, I select it and the system reboots from the external disk. Then I did the initial SuperDuper! Erase, full copy and make disk bootable. It initially formatted using Disk Utility as Mac OS Extended Journaled. This combo works flawlessly with SuperDuper!. I connect the external Hitachi via the USB 2.0 connector, as the macbookpro does not have eSATA connections. The case is an AMS Venus DS2 model 2215SESBk (SATA internal to eSATA+USB2.0) I bought another identical Hitachi raw drive (identical to the internal disk above) from OWC and also a case for the drive. I bought my SuperDuper! about 2 weeks ago.
My internal disk is Hitachi HTS723232L9A360 (320GB 7200rpm SATA) I'm using a macbookpro 2.4 GHz Intel Core 2 Duo, Leopard 10.5.6.
