I'm hoping someone can help with this organization project that I want to try. I'd like to buy a new external HD and step into the world of Lightroom. I plan to put my catalog of photos on the external HD, which Lightroom makes seemingly easy. The caveat is that I would like to encrypt the external HD with TrueCrypt. My question is, can I encrypt the whole external HD, and still have fluid functionality with LR on my computer, accessing the catalog on the external HD? Will I have to mount the drive first every time I use lightroom? Or is there a way to do this more easily. I am using a mac. Any advice would be greatly appreciated. Thanks.
