Product Specification and User Manual

The default Sanitize procedure is factory-preset to the Security Erase option (erase the media
without media fill).
The Master Command has the following layout:
Bits 6-7
: Subcommand selection
Value of 00b
: Execute default Sanitize procedure
Value of 01b
:
Execute 1 subcommand, defined in bits 0-1
Value of 10b
: Execute 2 subcommands, defined in bits 0-1 and 2-3
Value of 11b:
Execute 3 subcommands, defined in bits 0-1, 2-3 and 4-5
Attempting to save the default Sanitize configuration (option „D‟) using subcommand selection
00b will result in an aborted command and no changes will be made.
When Master Command specifies only 1 or 2 subcommands, parameters for the remaining
subcommands are reserved and should be set to 0 for compatibility with future versions.
For the default Sanitize procedure, all other bits in the Master Command and parameters1-3 are
reserved and should be set to 0 for compatibility with future versions.
Bits 0-1,
2-3
and
4-5
of the Master Command contain the following subcommands:
Value of 0
: Erase and fill with given character. The character is provided in the corresponding
parameter.
Value of 1
: Erase and fill with random data, several times. The number of erase/fill loops is
provided in the corresponding parameter. Zero number of loops means erase once and do not fill.
Only the 7 least significant bits in the parameter are used to specify the number of loops. The
most significant bit is reserved for future extensions.
Value of 2
or
3
: These subcommands are reserved for future extensions.
Parameter1
corresponds to the subcommand in bits 0-1.
Parameter2
corresponds to the subcommand in bits 2-3.
Parameter3
corresponds to the subcommand in bits 4-5.
Partition Mask
is either a bitmap of partitions to be sanitized or value 0. In the bitmap mode,
least-significant bit 1 corresponds to partition 0. Value of zero is a special value; it corresponds
to sanitizing the whole media regardless of partition configuration.
For example, Value of 0xF (or 1111 binary) corresponds to sanitizing of all 4 partitions,
Value of 0x8 (or 1000 binary) corresponds to sanitizing partition number 3,
Value of 0x1 (or 0001 binary) corresponds to sanitizing partition number 0,
Value of 0x5 (or 0101 binary) corresponds to sanitizing partitions 0 and 2,
Value of 0 (or 0000 binary) corresponds to sanitizing the whole media.
See Section 4.6.4 for additional information on sanitizing partitions.
