10.5: Install on a PPC Mac from an external USB Drive
Authored by: iconoplast on May 08, '12 09:13:46PM

Great Article.

I've already done this (thanks to this and other articles) back in February. I recently dropped my laptop again (doh!), and have had try to do this again.

Last time I succeeded, and this time I'm failing. The only difference in my method between last time and this is that I have a different external drive. Last time, I used a 160 gig desktop drive in USB enclosure, and this time I'm trying to use a WD 1 terabyte drive.

My trouble is that when I "dev ls", as per point 9. of this article, I don't get a "/Disk@1" showing up for the 1tb drive. Just to be sure it wasn't a different problem, I formatted a USB stick to Mac OSX Extended, and looked for it in Open Firmware, and it did indeed show up as a "/Disk@1".
(I restored the .dmg of 10.5 onto the USB stick, and tried booting from that, but my laptop kept giving me the "Circlebar" no-go symbol. Researching around on the web, it appears that flash sticks sometimes can't keep up with the computer's boot demands.)

Does anyone know why this would be? Like I said, nothing I've done has changed except the external drive.
One little difference I wonder about is that the first (successful) usb boot happened on a drive installed with Mac OSX Extended (not journaled), and the WD drive itself defies formatting that way.
When I try to format it as MOSXE using Disk Utility, I click on the physical drive in the left hand column, and it formats, creating a single partition on the physical drive, which it displays as a "child" underneath the physical drive. When I browse the physical drive again using Disk Utility (by clicking on the erase or partition tab), the WD physical drive shows up as MOSXE(journaled) and not simply MOSXE.
Could this have anything to do with why the drive won't show up under a usb device when I "dev ls" in Open Firmware?
