Parameter Value
Logical Object Number Logical block address
Compression Status 0h = The drive is incapable of determining if the logical object
referenced has been compressed
Encryption Status • 1h = Drive is capable of determining if the logical block referenced
has been encrypted, but is not able to at this time, for example: not
read into the buffer, error, end of data
• 2h = Drive has determined the logical block is not a logical block
• 3h = Drive has determined the logical block is not encrypted
• 5h = Drive has determined the logical block is encrypted
• 6h = Drive has determined that the logical block is encrypted,
but the drive is either not enabled to decrypt or does not have the
correct key to decrypt the encrypted block
Algorithm Index 00h = Not valid, for example: encryption and decryption not enabled
01h = Default algorithm index
EMES Encryption mode external status
0 = Not supported
