I want to password protect the contents of an external hard disk. I found only one article on such a thing, and of course the authors arrogantly assume you are a Windows user. So it's of no use to me. But I was hoping someone here knew of a way to do this on a Mac. http://www.ehow.com/how_6774220_install-portable-hard-disk-drive.html The disk is formatted as OS X Extended (Journaled). I realize a password protected .dmg could be made and everything dragged in, but we're talking about 1TB of data here - seems like that would take forever to mount and just be impractical. Please let me know of any ideas you guys have!
