An external disk with a bootable system + the needed utilities -
DiskWarrior, iDefrag, MainMenu, Onyx, Cocktail or whatever other
maintenance apps you wanna use? - YES you can! Just install OS X to the
external disk and install the wanted/needed utilities. The only thing
you should note - as I've already written - is that USB will be
definitely slower than Firewire.

In the old OS 8.x and 9.x days I made such a disk with a Mac OS 8.6 and
later on a OS 9.1 on a small 2,1gb LaCie d2 SCSI disk, which I could
move around from my PM 7200, PM 7600 and 2x PM 9600, and this worked
just fine.

Cheers, Erik Richard
