Ok here we go! I have a 2.5ghz 17 mbp with 320gb hdd, 4gb ram. My question is I've setup time machine with a 250gb external hdd and I have 500gb 2.5 externa hdd for transfering files to and from my pc. Today I just got another 500gb wd mybook but this time I want to do something like making an image of my mbp hdd so if something goes bad with my mbp's hdd,I'll just swap it and restore cos I don't have the os x cd. but don't know what's the best solution for that, cos I'm like a week of using a mac. So if it was you, what will you do with all these hdds? I mean backup wise??
