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 the 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 parameters 1-3 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.
The Partition Mask is either a bitmap of partitions to be sanitized or value 0. In 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:
o
Value of 0xF (or 1111 binary) corresponds to sanitizing of all 4 partitions
o
Value of 0x8 (or 1000 binary) corresponds to sanitizing partition number 3
o
Value of 0x1 (or 0001 binary) corresponds to sanitizing partition number 0
o
Value of 0x5 (or 0101 binary) corresponds to sanitizing partitions 0 and 2
o
Value of 0 (or 0000 binary) corresponds to sanitizing the whole media
