the drive is returned to the default factory state. It is then immediately ready for disposal or repurpos- ing.

The ATA Security Erase Unit Command provides for normal and enhanced erase modes as follows:

Table 6:	ATA Security Erase Unit bits

Word		Content

0		Control word

		Bit 0	Identifier	0 = Compare User password

				1 = Compare Master password

		Bit 1	Erase mode	0 = Normal Erase

				1 = Enhanced Erase

		Bit (15:2)	Reserved

1 - 16		Password (32 bytes)

17 - 255		Reserved

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.3 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.
