Page 191 highlights

Sector (HOB=0) Number LBA (7:0) of the address of the first unrecoverable error. Sector (HOB=1) Number LBA (31:24) of the address of the first unrecoverable error. Cylinder Low (HOB=0) LBA (15:8) of the address of the first unrecoverable error. Cylinder Low (HOB=1) LBA (39:32) of the address of the first unrecoverable error. Cylinder (HOB=0) High LBA (23:16) of the address of the first unrecoverable error. Cylinder (HOB=1) High LBA (47:40) of the address of the first unrecoverable error. CCTO (Error, bit 0) CCTO bit shall be set to one if a Command Completion Time Limit Out error has occurred. SE (Status, bit 5) SE (Stream Error) shall be set to one if an error has occurred during the execution of the command and the RC bit is set to one. In this case the LBA returned in the Sector Number registers shall be the address of the first sector in error, and the Sector Count registers shall contain the number of consecutive sectors that may contain errors. If the RC bit is set to one when the command is issued and a UNC, IDNF, ABRT, or CCTO error occurs, the SE bit shall be set to one, the ERR bit shall be cleared to zero, and the bits that would normally be set in the Error register shall be set in the error log. DWE (Status, bit 4) DWE (Deferred Write Error) shall be set to one if an error was detected in a deferred write to the media for a previous Write Stream DMA or Write Stream PIO command. This error is from a previously issued command. If DWE is set to one, the location of the deferred error is only reported in the Write Stream error log.

Sector
Number
(HOB=0)
LBA (7:0) of the address of the first unrecoverable error.
Sector
Number
(HOB=1)
LBA (31:24) of the address of the first unrecoverable error.
Cylinder Low (HOB=0)
LBA (15:8) of the address of the first unrecoverable error.
Cylinder Low (HOB=1)
LBA (39:32) of the address of the first unrecoverable error.
Cylinder
High
(HOB=0)
LBA (23:16) of the address of the first unrecoverable error.
Cylinder
High
(HOB=1)
LBA (47:40) of the address of the first unrecoverable error.
CCTO (Error, bit 0)
CCTO bit shall be set to one if a Command Completion Time
Limit Out error has occurred.
SE (Status, bit 5)
SE (Stream Error) shall be set to one if an error has
occurred during the execution of the command and the RC bit
is set to one.
In this case the LBA returned in the Sector
Number registers shall be the address of the first sector in
error, and the Sector Count registers shall contain the
number of consecutive sectors that may contain errors.
If
the RC bit is set to one when the command is issued and a
UNC, IDNF, ABRT, or CCTO error occurs, the SE bit shall be
set to one, the ERR bit shall be cleared to zero, and the
bits that would normally be set in the Error register shall
be set in the error log.
DWE (Status, bit 4)
DWE (Deferred Write Error) shall be set to one if an error
was detected in a deferred write to the media for a previous
Write Stream DMA or Write Stream PIO command.
This error is
from a previously issued command.
If DWE is set to one, the
location of the deferred error is only reported in the Write
Stream error log.
