SMART error logging
If the device detects an unrecoverable error during execution of a command
received from the host, the device registers the error information in the SMART
Summary Error Log (see Table 5.18) and the SMART Comprehensive Error Log
(see Table 5.19), and saves the information on media.
The host issues the SMART Read Log Sector sub-command (Features field = D5h,
Sector Number field = 01h, Sector Count field = 01h) and can read the SMART
Summary Error Log.
The host issues the SMART Read Log Sector sub-command (Features field = D5h,
Sector Number field = 02h, Sector Count field = 33h) and can read the SMART
Comprehensive Error Log.
