00 Unrecovered Read Error Unrecovered read error occurs during reading data field
(LBA Miscompare Error detected by SCSI portion)
3
01 Read retries exhausted Unrecovered error was detected during data read (retry out). 3, B
02 Error too long to correct Unrecovered error was detected during data read (BCRC error
detected by SCSI)
3, B
11
04 Unrecovered read error, auto
reallocation failed
Auto allocation failed during read. 3
13 00 Sync Byte not found for Data
field
SB (Sync Byte) could not be detected in the Data area. 1, 3, B
00 Record entity not found Expected data from a sector was undetected. (LBA compare
error detected by FMT)
1, 3, B14
01 Record not found The target data block (sector) could not be detected. 1, 3, B
01 Mechanical positioning Error A seek error occurred in the drive. 1, 3, B15
02 Positioning Error detected by
read of medium
LBA did not match due to Cylinder number’s mismatch. 1, 3, B
01 Recovered data with retries A data error was recovered from by reading was retried. 1
02 Recovered data with positive
head offset
A data error was recovered by read retry with offsetting head to
positive direction.
1
03 Recovered data with negative
head offset
A data error was recovered by read retry with offsetting head to
negative direction.
1
06 Recovered data without ECC:
data auto-reallocated
Automatic alternate allocation was applied without ECC
correcting a data error.
1
17
08 Recovered data without ECC:
recommended rewrite
Rewriting to the same sector was performed without ECC
correcting a data error.
1
18 00 Recovered Data with Error
Correction Applied
A data error was recovered by read retry with ECC corrercting. 1
02 Defect list error in primary list An error was detected during reading of the defect list (P List). 3
03 Defect list error in grown list An error was detected during reading of the defect list (G List). 3
80 Log information read error An error was detected during reading of statistical information. 3
81 Log information write error A write error was detected during writing of statistical
information.
3
84 Mode Select SA write Error An error was detected during writing of SA information (Mode
Select Paramenter)
3
