ECCNG 
Indicates that error correction was not possible. 
This bit is also set to 1 on detection of a short sector. 
3 ST_ECCP 
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. 
2 ST_ECCQ 
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).  
This bit is set to 1 when the result of syndrome 
calculation for Q parity is other than all 0s. 
ST_EDC1  0 
Indicates that the result of the EDC check before ECC 
correction was ‘fail’. 
This bit is also set to 1 if a short sector is encountered 
while EDC is enabled. 
ST_EDC2  0 
Indicates that the result of the EDC check after ECC 
correction was ‘fail’.
