Hey fellas, I've been looking into this a lot the passed few days, but there are a few answers I just can't find. First of all, I know how to physically take apart my mac and put the new hard drive in. I have the new hard drive, and the tools I need. The method I chose (before I looked into how to xfer data using macs) was to use time machine to make a backup of my entire hard drive on an external, which I did successfully. However, before I take apart my mac and instal the new hard drive, there are a few things I want to be clear on, and I can't find the answers to. Will I need the leopard OS disc for the new hard drive? Or does time capsule back up the OS as well, and give me some sort of prompt (doubtful)? I have the pre late 2008 macbook pro, and it came with leopard. I haven't upgraded for several reasons I won't get into. My question now is, should I have the leopard OS disc? SHouldn't something like that have come with my mac? I ask because I feel like I should have one, but I don't remember getting one and can't find it anywhere. I always keep things like that. And lastly, if I don't have the leopard OS disc, what do you think is the cheapest way for me to back up and xfer my data? I have external hard drives, my new hard drive, and my old hard drive. Would it be cheaper for me to buy one of those things that directly xfers the data from one internal drive to another, or to buy another leopard disc? Is there a way I can just order the leopard disc I should have already for cheaper? Thanks a lot!
