Techopedia Explains Hard Drive Encryption

Specialized software is used to encrypt the data written to the hard drive. When a file is read, it must be decrypted by the software while leaving all the other data on the drive encrypted. The encryption/decryption process does not affect other applications or programs. The encryption/decryption process is invisible to the user, although it may cause the computer's processing times to be slower.
