the drive is returned to the default factory state. It is then immediately ready for disposal or repurposing. The ATA Security Erase Unit Command provides for normal and enhanced erase modes as follows: Table 6: ATA Security Erase Unit bits Word 0 1 - 16 17 - 255 Content Control word Bit 0 Identifier Bit 1 Erase mode Bit (15:2) Reserved Password (32 bytes) Reserved 0 = Compare User password 1 = Compare Master password 0 = Normal Erase 1 = Enhanced Erase Choosing enhanced erase mode will simply perform the cryptographic erase described above, and return status 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 choosing enhanced erase. Momentus 5400 FDE.4 SATA Product Manual, Rev. B 27
