Choosing enhanced erase mode will simply perform the cryptographic erase described above, and return sta-
tus almost immediately. This is the recommended option.
To maintain consistency with the ATA Security specification, Momentus 5400 FDE.4 SATA drives provide an
option to perform the Normal Erase mode.
Choosing normal erase will result in the drive performing the cryptographic erase which is the same as choos-
ing enhanced erase.
