Description
4 ST_
ECCNG
0
R
Indicates that error correction was not possible.
This bit is also set to 1 on detection of a short sector.
3 ST_ECCP
0
R
Indicates
that
P-parity errors were not corrected in ECC
correction.
This bit is only valid when synchronization is normal
(the sector is neither short nor long).

This bit is set to 1 when the result of syndrome
calculation for P parity is non-0.
calculation for P parity is non-0.
2 ST_ECCQ
0
R
Indicates
that
Q-parity errors were not corrected in ECC
correction.
This bit is only valid when synchronization is normal
(the sector is neither short nor long).
(the sector is neither short nor long).
This bit is set to 1 when the result of syndrome
calculation for Q parity is other than all 0s.
calculation for Q parity is other than all 0s.

correction was ‘fail’.
This bit is also set to 1 if a short sector is encountered
while EDC is enabled.
while EDC is enabled.
