when i bought my mac i also bought a Lacie hard drive but the first system it was connected to was windows just cuz i wanted to transfer all of my old stuff to my new mac... so..at first i had an option to divide the drive to a mac and windows so that i will be able to use it for both. i agreed and now i have like 400 GB that i can fit things ONLY FROM windows to the drive and the rest is for mac. today i wanna format my mac. i feel like its been working slowly.. the thing is that i can't back it up cuz i only have 100 GB for a mac space and i need all of drive.. please can someone tell me how to format the drive that i will get that option to divide it again?!? (a guide would be great!) and another thing, how can i backup the photos from "iphoto" simply to the drive as files and NOT through time machine??
