Yesterday, I wrote a tip about using FileVault 2 encryption in Mac OS X Lion to encrypt a variety of external devices and SD cards. Although I like FileVault 2, I mentioned that it had some caveats.
The most glaring caveat is that media encrypted using FileVault 2 won’t work on other platforms. That might be fine in a home or business that uses only Macs, but it isn’t fine if you are also using computers running Windows or Linux.
Today I’ll show you how to encrypt drives that will work on computers running Mac OS X, Windows and Linux.
