Подскажите, что значит атрибут "Reported errors count" (на скрине он в самом низу). Перевод говорит, что это "количество зарегистрированных ошибок", но что это за ошибки, из-за чего возникают и можно ли исправить? Raw-значение растёт на единицу через каждые несколько месяцев. Все остальные параметры говорят, что здоровье диска в порядке.
Так же интересует атрибут "Second temperature". Что он означает и для чего нужен, если температуру показывает атрибут "Ariflow temperature"?

First of all, here's a link to a good introduction to S.M.A.R.T. (including its problems): https://en.wikipedia.org/wiki/S.M.A.R.T. As mentioned in this introduction, a problem with the S.M.A.R.T. specification is that, with only a few exceptions, there are no set requirements regarding what attributes are to be provided and how they are used. Implementations differ considerably across the many manufacturers. A common fault in tools that display S.M.A.R.T. attributes is that they do not take into account the differences in attribute usage on a vendor-by-vendor basis. As a result, they often display the wrong title for the attribute and/or misinterpret the raw data provided for this attribute.
Next, let's look at the datasheet for the Intel 545s Series SSDs. I found a copy online here: **** Link Removed **** (this is actually an Intel-confidential document that really shouldn't be there).
From this document, I extracted a summary of the attributes supported:
As you can see from the datasheet (and my summary), some of the attributes listed by your tool are handled incorrectly and others are not even supported by these drives.
Now, to your particular questions,
- For this drive series, Intel uses only attribute 190 to provide drive temperatures. I have no idea where this tool came up with this attribute 236, but it isn't supported or exposed by this drive series.
- Similarly, attribute 252 is not one exposed by the drive series, so I cannot tell you what it means.
Hope this helps,
...S
