Block Address. This field contains the block address the disk drive was attempting to access
when the error occurred. If the PHYS bit in the CDB is set to zero (0), this is a logical block
address. If PHYS is set to one (1), this is a physical block address. The address format is
similar to that described for the Data Error Log entry.
Internal Device Status. This byte contains an error code corresponding to the Additional
Sense code returned by the REQUEST SENSE command. If the error was recoverable, the
most significant bit will be set (1). If the error was unrecoverable, the most significant bit will
be zero (0).
Vendor Unique Status. The vendor unique status codes are listed in Appendix C.
Field Replaceable Unit (FRU). Returned as zeros.
