Easily boot from USB 2.0 drives on PowerPC Macs
Authored by: willeyeam on Dec 28, '06 04:23:25PM

Not so easy as it makes it sound.
especially for someone in my position, whose internal hard drive is more than twice the size of their external. for me, i have 350gigs worth on my internal drive, but my external is only 150gigs.
So I created my own custom copy script in superduper, to exclude my the folders that contain large amounts of data i don't need backed up.
This cut down the size to something that fits. all of the ignored folders are in my home folder, so i don't think it should inhibit the system from booting. Superduper says it did it all, but alas, i cannot get it to appear in startup disk panel, or by holding option at startup, or even with the older Open Firmware bit.
I have a G5 quad powermac, 10.4.8. WHAT AM I MISSING!!

i have a powerbook G4 1.5Ghz with 10.4.8. I used SuperDuper today to copy my computer hard drive to a Western Digital My Book USB2 drive. SuperDuper said at the end of the process that the drive was made bootable, but the SuperDuper website is clear that this should not work on a USB drive. After the copy was made, i noticed that the number of files copied was a little less than the total number of files, whatever that means. I checked in StartUp Disk/System Preferences and the USB2 drive partition with the system did not show up as a choice of start up drives. Only the computer hard drive showed up with the system. After I read this hint, i tried holding down the Option key and restarting but it didn't bring up the external disk partition--the only choice that came up was the computer hard drive system folder. I tried it twice. I may be doing something incorrectly.
