Which format to use to make bootable external for Intel Mac

[mobydisk]

Hi Dave,

Just got a 500GB FW400/USB 2.0 external drive and I want to partition it to use with SD with my Mac Pro. So, I just want to clarify my plan.

1. I should connect the drive via USB 2.0 correct so it will be Intel Mac bootable?

2. I should partition the drive using Disk Utility with the SD clone being about 10% larger than the internal boot drive (assuming I will keep 10% free in the internal boot drive)?

3. The format for the external drive should be Mac OS X Extended (Journaled)?

4. The partition scheme should be APM so I can use it to boot the Mac Pro and if necessary my G4 Powerbook?

I posed these as questions since I have my doubts that this plan is correct. What do you recommend?

Thanks and Happy Holidays to you and family,
Marianne
