![]() My only recommendation is take excellent notes as you triage things and know this process wasn’t a slam dunk when new due to several very technical details down to which of several manufacturers made the same “part” inside your Mac. You may have to have multiple devices now to get repeatable results if age is making them less consistent. That was when everything was new and hardware failures in the boards and cables and drives (and let’s limo in aging / flakey devices with failing ones). This all interacted in ways that made booting even more fussy than if the drive worked after the system was up and running.īrands like LaCie and G-TECH tended to work more universally than others, but it was hit or miss if one drive would work with any arbitrary Mac. The problem wasn’t so much the process of restoring and blessing as much as the issue is firmware drivers and differences in chipsets on Macs as well as controllers in the USB and FireWire external drives. We did this all the time back in the day and it was very fussy. I'm going to get a couple SATA to IDE converter cards, load the installer disk onto one of these SSD SATA drives, plug it into the internal drive interface and install onto a second, empty one. ![]() I know that an older Intel-based MacBook Pro running OS 10.6 won't format or partition that when hooked up via USB, and indications are that the error has to do with the USB interface. If no one has any insight, I'm considering the possibility that the firmware for the external drive case FireWire port is somehow not readable by 2001 or so G4 PowerMac. I then want to be able to run the installer and load OS 10.4 orġ0.5, and OS 9 onto other partitions on that external HD with FireWire and designate it as the startup volume for that machine. ![]() Have that external HD be recognized by the G4 PowerMac when I boot Have a bootable installation partition with the OS X 10.4 (or 10.5)īe able to build that partition using an Intel Mac. USING AN EXTERNAL HD with a FireWire port. Is this an issue with trying to build this from an Intel-based Mac? I'd love to just run the installer and put it onto that hard drive on a partition, but I can't run that installer on an Intel-based Mac.ĮDIT: PLEASE DO NOT SUGGEST THE OTHER SIMILARLY TITLED QUESTION, IT IS NOTHING CLOSE TO THE SAME. When I hook it up to the firewire port and boot the G4 holding the "Option" key down, it doesn't bring up anything on the screen where you would select which drive/volume you want to boot from. dmg file, and the partition on my hard drive looks like and behaves like an installation disk (formatted the Hard Drive with Mac OS Extended, Journaled, Apple Partition map format, not GUID). I did it using Terminal and the "sudo asr" command, copied that. I've been trying to load an image of the installation disk (.dmg) onto an external firewire drive. I need that old Mac to be able to run OS X and OS 9, because I can't retrieve and convert some of the files from the secondary hard drive unless I can run the old programs on the old OS (Like the old Hypercard stacks). I had a hard drive failure on my old PowerPC G4 Mac.
