WABEREQ field
If a write medium operation has not been performed on a logical block referenced by a mapped LBA since a sanitize block erase operation was
performed, and no other error occurs during the processing of a read command specifying that LBA, then the write after block erase required
(WABEREQ) field indicates the device server behavior (see table 442).
WACEREQ field
If a write medium operation has not been performed on a logical block referenced by a mapped LBA since a sanitize cryptographic erase oper-
ation was performed, and no other error occurs during the processing of a read command specifying that LBA, then the write after cryp-
tographic erase required (WACEREQ) field indicates the device server behavior (see table 443).
NOMINAL FORM FACTOR field
The NOMINAL FORM FACTOR field indicates the nominal form factor of the device containing the logical unit and is defined in Table 444.

Code Definition
00b Not specified
01b The device server completes the read command specifying that LBA with GOOD status and any data
transferred to the Data-In Buffer is indeterminate.
10b The device server terminates the read command specifying that LBA with CHECK CONDITION status with
sense key set to MEDIUM ERROR and the additional sense code set to an appropriate value other than WRITE
AFTER SANITIZE REQUIRED (e.g., ID CRC OR ECC ERROR).
11b The device server terminates the read command specifying that LBA with CHECK CONDITION status with
sense key set to MEDIUM ERROR and the additional sense code set to WRITE AFTER SANITIZE REQUIRED.
