[smartmontools-support] How to understand smartctl -x output lines concerning the log?

Hi,

how to understand the following lines of smartctl -x output?


*SMART Extended Comprehensive Error Log Version: 1 (1 sectors) No Errors
Logged*

*SMART Extended Self-test Log Version: 1 (1 sectors)*
Especially, what is the meaning of "1 sectors"? I hope this is not the
number of bad/failing sectors, right?

On another drive, I get the following:
SMART Extended Comprehensive Error Log Version: 1 (64 sectors)
No Errors Logged

SMART Extended Self-test Log Version: 1 (1 sectors)

And another one:
SMART Extended Comprehensive Error Log Version: 1 (6 sectors)
No Errors Logged

SMART Extended Self-test Log Version: 1 (1 sectors)

So the numbers differ. As far as I know all three drives have no
bad/failing sectors.

For the reference, I enclose the full output for the first drive at the end
of the message.

Thank you in advance for your explanation.
D. Wroblewski
