a. Compare a hash of the original drive to the drive image.
b. Compare the file size on disk of the original drive to the space taken up by the drive image.
c. Compare the vendor's drive size listing to the space taken up by the drive image.
d. Use PGP to encrypt the drive and image and make sure that both encrypted versions match.
