I have a 2.5" Western Digital drive which I connect to my laptop via one of the USB ports. I was just wondering what it would take to encrypt that drive. Currently, none of the other drives on my system are encrypted, and I only want to encrypt the one connected to the USB port. When I purchased the laptop directly from Dell a couple of weeks ago, I elected to do so without encrypting the disk, so I'm assuming there's no encryption software installed. If after encrypting the drive I can "see" it only from the laptop, that's fine with me. Any suggestions?
