Link: Full disk encryption - Wikipedia, the free encyclopedia


Full disk encryption (or whole disk encryption) is a kind of disk encryption software or hardware which encrypts every bit of data that goes on a disk or disk volume. The term “full disk encryption” is often used to signify that everything on a disk is encrypted, including the programs that can encrypt bootable operating system partitions. But they must still leave the master boot record (MBR), and thus part of the disk, unencrypted. There are, however, hardware-based full disk encryption systems that can truly encrypt the entire boot disk, including the MBR.
