I have my original Late 2008 Macbook Pro and it hasn't been formatted since. Having recently upgraded to Lion, I personally feel it is a little slower, possibly due to heavy disk fragmentation, thus I have decided to carry out a clean install of Lion. However...! I have tried searching for some guidance on the exact procedure, but it gets a little complicated on the following questions: 1. If, say, I realised I forgot a precious document and assuming I have backed up using Time Machine before my format, could I pull off a specific item/folder through Time Machine post my format? 2. Are there any files (other than the typical Music, Photos, Documents) that are hidden which I should really consider? 3. Does anybody know of any good guides/tips I should read before doing this? I have tried searching, but clearly I am not very good at finding content?! Thanks for your help!!!
