Securing External Drives and Files on them?

[netdog]

How can I secure an external drive and individual files on an external drive via a password? Is there a way to encrypt? Are there other means available? Included in that, I would love to support a small USB key-drive in case I were to lose it somewhere.

Thanks all.

Make a disk image with Disk Utility. Use AES-128 encryption. Assign a password. Copy the image file to your external drive. Now you just have to mount the image whenever you plug it into a computer. Remember to eject the mounted image, then eject the mounted drive.

It can be broken, but with a good password the cracker will be dead by the time they get the password.
