linux - Smartclt - No self-tests have been logged

Good night,

The following command is scheduled in the crontab: 15 10,13,19,23 * * * /usr/local/bin/smartctlLogger.sh

smartctl -i -l selftest -l error -H -t short

However, in one of the tests performed at 23, there was the following return:

SMART Self-test lo g structure revision number 0
Warning: ATA Specification requires self-test log structure revision number = 1
No self-tests have been logged

Not showing the records below, as they usually appear in the log:

Warning: ATA Specification requires self-test log structure revision number = 1
Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error

1 Short offline Completed without error 00% 21258 -

2 Short offline Completed without error 00% 21255 -

3 Short offline Completed without error 00% 21252 -

4 Short offline Completed without error 00% 21242 -
(...)

The disk is: Model Family: Quantum Fireball lct20, Device Model: QUANTUM FIREBALLlct20 20, Firmware Version: APL.0900.

My doubts are, because no self-tests have been logged (No self-tests have been logged), and because it also appears:

SMART Self-test log structure revision number 0
Warning: ATA Specification requires self-test log structure revision number = 1

Other disks appear only: SMART Self-test log structure revision number 1
