I have a 80 gb Powerbook, with about 30 gb of info I should have a back-up copy of... What do you recommend I do to do this... I am trying to save $$ What is the best bang for my buck?
I dunno where you get your DVDs, but my 16x verbatim dvdrs were <25 cents. the DL dvdrs go for about $1-2 each.
a hard drive (External) is the way to go, and small ones are pretty cheap. You could build your own 80gb external for maybe $70-90 ($40 for hard drive, $30 for enclosure) if you wanted to.
its the filesystem that matters slightly more than hardware compatibility (as, provided you have whatever you need (usb, firewire, SATA, etc.), odds are it will work).
