hi, well i have got myself a nice 160gb lacie d2 esternal hard drive. i want to back up all of my hardrive on my powerbook (40gb about 10gb left on it). basically, how should i go about it. i have a copy of silverkeeper that i got with it and also a copy of carbon copy cloner. should i create a partition? if so how big? what should i use to back it up? any other programme? should i create my back up to be bootable? if so how? anything else you may want to add! thanks!
