Cylinder High Previous LBA (47:40). Input Parameters From The Device 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 WC 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 WC bit is set to one when the command is issued and an 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. 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. Deskstar 7K400 Hard Disk Drive Specification 248

Cylinder High
Previous
LBA (47:40).
Input Parameters From The Device
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 WC 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 WC bit is set to one when the command is issued and an
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.
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.
