Hard Disk Monitoring

I open a hard disk offline status, but the information is not correct.
The health value is displayed 17% in the upright of page, and the hard disk list also display 17%, but actually, the true value is 16% (show in the graph). Just like the "power on time" of SMART attribute，in the SMART page, the "power on time" is 5357, but actually, it should be 7660（shown in the graph）

Thanks, but there may be no bug of course: the Health % on the bottom graph shows the worst (lowest) Health % recorded for each days - while the Health % bar on the top and the leftmost area shows the latest Health % value.
These may be not always same.

The "power on time" seems interesting. Please use Report menu -> Send test report to developer option, as then I can check.

I check my drive's health, I found the health of my hard disk is 17% at 2021/12/21 when the first record generated, and then fall to 16% at 2021/12/28 until now.

When talk about SMART value of offline hard disk, it's not only the "power on time", but also every value of SMART attirbut, it seems the software shows the value of the first time record, instead of the value of the last record. below is some value. The screenshots below shows the problem.

Thanks for the report and the images. Seems so interesting, I'll examine the situation and investigate/reproduce and will check how to improve the situation.
Thanks for your attention!
