Features Secondary Operation Code
Sector Count Host Allocated buffer size
Sector Number block number(0:7
Cylinder Low block number(7:15)
Cylinder High block number(16:23)
Device/Head NA NA NA DEV block number(23:27)
Command 83h
There are evif secondary operation codes:

0x00 : GET_DATA_LENGTH returns the number of blocks that failed to erase in the SSD
registers, in the block number filed.

0x01 : GET_FIRST_DATA sends the failed to sanitize data from the first block. The SSD
aborts the command if the sanitize command with secondary operation code 0x22 has not
been issued prior to the data retrieval request.

0x02 : GET_NEXT_DATA sends the next data in the pipeline. The SSD aborts the
command if it reaches the end of the data, or if the sanitize command with secondary
operation code 0x22 has not been issued prior to the data retrieval request.

0x03 : GET_BLOCK_DATA sends the data of the requested block. The SSD aborts the
command if the sanitize command with secondary operation code 0x22 has not been issued
prior to the data retrieval request.

0x04 : GET_BLOCK_NEXT_DATA sends the next data in the pipeline from a specific
block. The SSD aborts the command if it reaches end of the data, or if the sanitize command
with secondary operation code 0x22 has not been issued prior to the data retrieval request.
4.6.2. Security Erase Functionality
The Security Erase option enables quickly erasing all the data stored on the SSD. This function is
activated by the vendor-unique Sanitize command (see Section ‎4.6.1) or via the Sanitize
hardware interrupt triggered by the Secure Erase header (if available).
The time required to perform the security erase depends on the disk Capacity and the type of
flash components being used. Table 14 describes typical time required to complete the security
erase for typical densities.
