[QUOTE="p1p3r, post: 608657, member: 29569"] I'm not a new switcher, but I feel like this is a n00b question. (I'm running Leopard, keep in mind!) I'm lending out my 500GB external HD and I'd like to lock things up before giving it away. I understand the basics of using the Disk Utility to create a .dmg that opens a password locked folder... I just have some questions about it! 1. The "Volume Size" when creating the new Disk Image... if I choose 100MB, will this folder only hold that much? So I should make it like... 200GB-ish? And if I make it Sparse, it will shrink accordingly so it doesn't take up too much space, right? (Just trying to make sure I'm not way off, here!) 2. I don't understand the whole Journaled thing... what Volume Format should I choose for what reasons? 3. There are a TON of choices for Partitions, and I know I just want one... but there are options, what should I choose?! DO I need a "map"? Thanks for the help! [/QUOTE]
