If you're encrypting the data on your hard drive using OS-level software encryption (e.g. Windows EFS, Vista BitBlocker, MacOS FileVault, Linux DM-Crypt, or TrueCrypt ), then a research study at Princeton University, partially funded by the Department of Homeland Security, has figured out how to read that data without your password. Well, that's just great.
