www.seagate.com Direct Access Block commands (SPC-5 and SBC-4)
If the INVERT bit is set to one and:
a) the OVERWRITE COUNT field is an even number, then the pattern used for the first write pass shall consist of:
A) the user data shall be set to the inversion of the INITIALIZATION PATTERN data; and
B) protection information bytes, if any, shall be set to 0000_0000_0000_0000h; or
b) the OVERWRITE COUNT field is an odd number, then the pattern used for the first write pass shall consist of:
A) the user data is set to the INITIALIZATION PATTERN data; and
B) protection information bytes, if any, shall be set to FFFF_FFFF_FFFF_FFFFh.
Following a successful sanitize overwrite service action operation:
a) the medium shall not be format corrupt;
b) protection information, if any, set to FFFF_FFFF_FFFF_FFFFh; and
c) read operations should complete without error.
3.41.4 SANITIZE command with BLOCK ERASE service action
The BLOCK ERASE service action (see table 170) performs a sanitize operation using the block erase method (see SBC-4).
After successful completion of a sanitize block erase, the device server:
a) may terminate commands that perform read operations to mapped LBAs with:
A) CHECK CONDITION status with sense key set to MEDIUM ERROR and the appropriate additional sense code for the
condition; or
B) if the logical unit is formatted with protection information, CHECK CONDITION status with sense key set to ABORTED
COMMAND and additional sense code set to one of the protection information check codes shown in Table 98;
and
b) should complete read operations to unmapped LBAs without error. (see SBC-4)
3.41.5 SANITIZE command with CRYPTOGRAPHIC ERASE service action
The CRYPTOGRAPHIC ERASE service action (see table 170) performs a sanitize operation using the cryptographic erase method
(see
SBC-4.
After successful completion of the cryptographic erase operation:
a) if any LBA is mapped and if the logical unit is formatted with protection information, then the device server may terminate read opera-
tions with CHECK CONDITION status with sense key set to ABORTED COMMAND and additional sense code set to one of the protection
information check codes shown in
Table 98; and
b) the device server shall process unmapped LBAs as required by logical block provisioning management.
3.41.6 SANITIZE command with EXIT FAILURE MODE service action
The EXIT FAILURE MODE service action (see table 98) requests that the device server complete a sanitize operation which
completed with an error as if the sanitize operation completed without an error (see
SBC-4).
After successful completion of a SANITIZE command with the EXIT FAILURE MODE service action:
a) if any LBA is mapped (see SBC-4), and the logical unit is formatted with protection information, then the device server may terminate
commands that perform read operations to mapped LBAs with CHECK CONDITION status with the sense key set to ABORTED COM
-
MAND and the additional sense code set to one of the codes defined in Table 98; and
b) the device server should complete read operations to unmapped LBAs without error (see SBC-4).
