5.3 Host Commands
(41) READ LOG EXT (X'2F')
(4) The sync byte indicating the beginning of a sector was not found
(ST = 51h, ER = 01h).
The READ LOG EXTEND command reads versatile log data. Versatile log data
includes the Extended SMART Comprehensive Error log, the Extended SMART
Self-test log, and the SMART Selective log. The effectiveness of the log types
depends on customization. For the protocol concerning data transfers, see Section
5.4.
The number of the log to be read is specified as the Log address. For log data
consisting of multiple sectors, a sector offset can be specified as an instruction so
that data transfer starts from the specified sector. The number of sectors to be
transferred is specified as the Sector count.
If an error occurs in the FP Queued protocol, Read Log Ext log page 10h
containing the error information is transferred. This Read Log Ext log page can be
read by specifying Sector offset = 00h, Sector count = 01h, and Log address =
10h. For the data format of Read Log Ext log page 10h, see Table 5.40.
The events of the PHY level on an interface are collected and it registers with
Read Log Extend page 11h. This Read Log Ext log page can be read by specifying
Sector offset = 00h, Sector count = 01h, and Log address = 11h. For the data
format of Read Log Ext log page 11h, see Table 5.42.
If this command is not supported, or if an invalid value is specified for the Log
address, Sector count, or Sector offset, the Aborted Command error occurs.

Error reporting conditions
(1) An error was detected during power-on processing (ST = 51h, ER = 04h).
(2) An error was detected during wake-up processing (in cases where wake-up
processing is required before execution of this command)
(ST = 51h, ER = 04h).
(3) An error that cannot be corrected with ECC occurred (ST = 51h, ER = 40h).
(5) An invalid log sector address or invalid Sector count (number of sectors to be
transferred) is specified (ST = 51h, ER = 04h).
(6) A SATA communication error occurred (ST = 51h, ER = 0Ch).
