![]() ![]() Is this perhaps the reason it will not boot on the PowerBooks (PPC G4 Macs)? If so, I have already determined that erasing the drive with Disc Utility (v11.1 under System 10.5.6) or using SuperDuper will not return it to an APM status. I used Disc Utility to check the partitioning information on the Seagate external and found it to be a GUID partition. I then tried to boot another newer PowerBook G4 with the faster 1.67 GHz processor using the same disc. The transfer rate in backing up the internal drive was exceptional, and took minimal time, but when I tried to boot from the drive using the Seagate's supplied FW 800 to 800 cable or FW 800 to 400 conversion cable, the PowerBook would not boot from the drive. I then went to work on a PowerBook G4, 1.5 GHz, making sure to use the firewire port, since I wanted it to be a bootable backup when I restarted from the backup. Works using USB 2 (requires two cables) or Firewire 400. This last week I put SuperDuper to work creating bootable backups of (first) a black Intel MacBook. Thank you for a wonderful, easy to use, and completely MUST HAVE tool.ĭuring Christmas I bought my sons and I the new Seagate FreeAgent Go for Mac 500GB external HD packages, thanks to Aston Kucher's TV ad's impression on my sons that this was a good thing, and MacWorld's review that it was a solid speedy drive. My work on myĬomputer is worth a lot more than the $95 for the disk and + $27 into the SuperDuper!. I formatted the OneTouch yesterday exactly that way I did the Hitachi, and the "default" behaviour was Master Boot Record mode.Īnyway, a few lessons learned and hopefully if others want to pick up a Maxtor OneTouch 4 320GB USB disk at Sam's Warehouse/Sam' Club, they were $95.īy having a few extra drives around, dedicated to doing nothing but SuperDuper!īackups, you really prevent catastrophic and timely downtime. Excellent! I'm still not sure why when I formatted my external Hitachi in the case, that it was formatted as GPT with no intervention on my part. I chose the orange USB disk icon and up it came. I'm now able to recognize and boot from the externally cloned Maxtor OneTouch 4 disk drive! By holding down my "Option" key on power up, and holding it a few seconds, I got two big icons right in the center of my screen. 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. ![]()
