So I want to use Time Machine with this WD MyBook World 1TB external drive NSB drive I bought. Thank God that I got frustrated setting up Time Machine and just installed their software so I could backup my computer because just days after I did, my hard drive bit it! Now that I've restored my system, I'd like to use Time Machine for my backup. My first question is, how do I do that on a network external?? I've read some articles, but it's a little foreign to me and I need a little more hand holding than what I've read. The second question is that now that I've partitioned the drive and have all this info. stored on it, do I have to erase it (partition it again) in order to have Time Machine be the backup? I have a MacBook with Snow Leopard installed and everything is up to date.
