Full Disk Encryption or Whole Disk Encryption is a phrase that was coined by Seagate to describe their encrypting hard drive. Under such a system, the entire contents of a hard drive are encrypted. This is different from Full Volume Encryption where only certain partitions are encrypted.

Some examples of full disk encryption:
