Table 27. Error Register
This register contains status from the last command executed by the device, or a diagnostic code.
At the completion of any command except Execute Device Diagnostic, the contents of this register
are valid always even if ERR=0 in the Status Register.
Following a power on, a reset, or completion of an Execute Device Diagnostic command, this register
contains a diagnostic code. See “Diagnostic Codes” on
Page 5
for the definition.
Bit Definitions
ICRCE (CRC)
Interface CRC Error. CRC=1 indicates a CRC error has occurred on the data bus during a
Ultra-DMA transfer.
UNC
Uncorrectable Data Error. UNC=1 indicates an uncorrectable data error has been
encountered.
IDNF (IDN)
ID Not Found. IDN=1 indicates the requested sector’s ID field could not be found.
ABRT (ABT)
Aborted Command. ABT=1 indicates the requested command has been aborted due to a
device status error or an invalid parameter in an output register.
TK0NF (T0N)
Track 0 Not Found. T0N=1 indicates track 0 was not found during a Recalibrate command.
AMNF (AMN)
Address Mark Not Found. AMN=1 indicates the data address mark has not been found after
finding the correct ID field for the requested sector.
This bit is obsolete.
11.6
Features Register
This register is command specific. This is used with the Set Features command, S.M.A.R.T. Function
Set command and Format Unit command.
11.7
LBA High Register
This register contains Bits 16-23. At the end of the command, this register is updated to reflect the
current LBA Bits 16-23.
When 48-bit addressing commands are used, the “most recently written” content contains LBA Bits
16-23, and the “previous content” contains Bits 40-47. The 48-bit Address feature set is described in
5.16.
11.8
LBA Low Register
This register contains Bits 0-7. At the end of the command, this register is updated to reflect the
current LBA Bits 0-7.
When 48-bit commands are used, the “most recently written” content contains LBA Bits 0-7, and the
“previous content” contains Bits 24-31.
11.9
LBA Mid Register
This register contains Bits 8-15. At the end of the command, this register is updated to reflect the
current LBA Bits 8-15.
When 48-bit addressing commands are used, the “most recently written” content contains LBA Bits
8-15, and the “previous content” contains Bits 32-39.
