Error Analysis

7.2.2Sense data (3-0C-03), (4-32-01), (4-40-xx), (4-C4-xx), and (4-44-xx)

Sense data (3-0C-03), (4-32-01), (4-40-xx), (4-C4-xx), and (4-44-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 a PCA or DE.

7.2.3Sense 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 4.3.2 “REASSIGN BLOCKS (07)” of the Interface Specifications.

If this error occurs in different blocks, a PCA or DE is faulty.

7.2.4Sense data (5-2x-xx), (B-44-xx), (B-47-xx), (B-4B-xx) and (B-4E-00): interface error

Sense data (5-2x-xx), (B-44-xx), (B-47-xx), (B-4B-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.

An interface error occurred.

A hardware error occurred inside HDDs.

If this error occurs, the PCA or the interface is faulty.
