Ok, I searched a bit, and didnt find the answer i am looking for. I have a 1.33 17" PB as my portable. For the first few months I owned it, it was my primary machine and used it for all my design work (photoshop, illustrator, FCS....). Anyway, I have since upgraded my home machine to a quad G5 and now basically only use my PB for travelling and to store all my music files and photos. I am down to 1 gig on my HD (80gig) and want to clean out the machine. I want to use the PB JUST for my music and images. I will no longer be running photoshop/illustrator or FCS ( as i am spoiled from my quad, and hate the speed of the PB for rendering). I have several FW drives, and have already backed up my itunes library and iphoto library. I want to now get the PB back to original state and will then move the itunes and iphoto libraries back on ( as they are all i want to keep on the PB). now, what is the best way to restore this machine? Over the years, i have moved tons of files into different areas of the HD, and FCP and motion have made their own render folders in different places. I just want to get rid of all that junk so the machine is music/photo only. Is there a way with disk utility that will in essence "reset" all the OS to its original install state? or do i need to do a clean install off the disc. I have the tiger family pack with 2 liscenses left. I just dont want to do a long install if there is an easier way to clean it all up. sorry for the long posts. thanks in advance to anyone that can help me out.
