7.2.2 Sense data (3-0C-03), (4-40-xx), and (4-C4-xx)
Sense data (3-0C-03), (4-40-xx), and (4-C4-xx) indicate one of the following:
• A target sector could not be detected using the sector counter.
• A seek process overran the specified time.
• A write to a disk terminated abnormally.
• An error occurred in power-on self-diagnosis.
• A drive error occurred.
The symptoms above are generally caused by an error in the PCA or the DE.
7.2.3 Sense data (1-1x-xx), (3-1x-xx) and (E-1D-00): Disk read error
If sense data (1-1x-xx), (3-1x-xx) or (E-1D-00) occurs frequently in a specific block of a disk,
there is disk damage that was not recorded in the media defect list. In this case, assign an alternate
block to the error-detected block using a REASSIGN BLOCKS command. For an explanation of
the REASSIGN BLOCKS command, refer to Subsection 3.3.2 “REASSIGN BLOCKS (07)” of the
SCSI Logical Interface Specifications.
If this error occurs in different blocks, the PCA or the DE is faulty.
7.2.4 Sense data (4-44-xx), (5-2x-xx), (5-3D-00), (5-90-00), (B-44-xx), (B-47-xx), (B-48-00),
(B-49-00), (B-4D-xx) and (B-4E-00): SCSI interface error
Sense data (5-2x-xx), (5-3D-00), (5-90-00), (B-44-xx), (B-47-xx), (B-48-xx), (B-49-00),
(B-4D-xx) and (B-4E-00) indicates one of the following symptoms:
• An invalid or unsupported command was issued, or invalid or unsupported parameters were
specified.
• A SCSI interface error occurred.
• A hardware error occurred inside the HDD.
• A parity error occurred in the SCSI bus.
If this error occurs, the PCA or the SCSI interface cable is faulty.
