Alrighty then. For the sake of clarity, let's say I want to use an external firewire on a non-PCI mac (gasp, OT!) like my iBook to boot from. Getting back to the original question, what makes one drive bootable over another that is not bootable given that they both contain the bootable system.


I have seen the recommendation several times in various forums to "make sure you get a bootable drive". What determines this???

For hard drives on modern Macs, this is irrelevant. All drives are bootable, they just need the drivers, which are installed by formattg the drive.


Macs prior to the G4 will not boot from any firewire device.

For PCI macs with SCSI drives, you need Mac drivers on the disk. Some disks are not supported by Drive Setup, and you either need to hack drive setup or use some utility like FWB's. Once formatted, they're bootable.

CD-ROM and CDRW drives are another story. SCSI ones are generally bootable, but only some ATA models are bootable. See XLR8Yourmac.com for a large list.
