depopulation revocation operations, the contents of the user data area may have no relation to the contents of the
user data area before the processing of the RESTORE ELEMENTS AND REBUILD command.
10.22.4.2 Actions Performed by Repurposing Depopulation Restorations
Repurposing depopulation restorations use the RESTORE ELEMENTS AND REBUILD command, that specifies that,
if depopulated storage elements are available for repurposing depopulation restoration, then the device:
a) shall perform a depopulation revocation operation;
b) shall perform a rebuild operation; and
c) may perform a user data initialization operation with inputs that do not change:
A. the logical sector size; or
B. logical to physical sector relationship;
A depopulation revocation operation, a rebuild operation, or a user data initialization operation shall not be terminated
by a COMRESET, hardware reset, or software reset.
If a depopulation revocation operation, a rebuild operation, or a user data initialization operation:
a) detects an error that prevents successful completion of that operation; or
b) is interrupted by a power-on reset,
then the device:
a) shall terminate that operation; and
b) may abort subsequent media access commands with the additional sense code set to DEPOPULATION
RESTORATION FAILED until a subsequent RESTORE ELEMENTS AND REBUILD command or a REMOVE
ELEMENT AND TRUNCATE command completes without error.
10.22.4.3 Depopulation Revocation Operations
To initiate a depopulation revocation operation the host issues a RESTORE ELEMENTS AND REBUILD command.
The depopulation revocation operation may continue after the command that initiated the depopulation revocation
operation returns command completion without error.
Sector reallocation may occur during depopulation revocation operations.
10.22.4.4 Rebuild Operations
A rebuild operation may change the native max address and the accessible max address.
After a rebuild operation completes all logical sectors on the device shall have the device logical block length and
number of logical sectors per physical sector in effect at the time of the processing of the RESTORE ELEMENTS
AND REBUILD command.
10.22.5 Interactions with Logs
While a device is performing a repurposing depopulation or a repurposing depopulation restoration, the device may
change the following logs:
a) the Pending Defects log (see Section 12.21.6);
