I have an Iomega 1TB external drive that i wish to have seperate password protected and encrypted areas. The files photos and media stored must be able to work on Mac or Windows. I have looked around a bit and see people mention Trucrypt but i believe it does not support Lion ? I also found Lockngo but can't find out much in the way of reviews and if it's worth the money. Is there a better or free alternative ? Thanks in advance.
