But I'm not so navigated as to understand the result, can someone explain it to me in simple terms?

Thanks

There is a great page on Wikipedia about this:

https://en.m.wikipedia.org/wiki/S.M.A.R.T.

Zitat

S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology; often written as SMART) is a monitoring system included in computer hard disk drives (HDDs), solid-state drives (SSDs), and eMMC drives.

Its primary function is to detect and report various indicators of drive reliability with the intent of anticipating imminent hardware failures.

When S.M.A.R.T. data indicates a possible imminent drive failure, software running on the host system may notify the user so preventative action can be taken to prevent data loss, and the failing drive can be replaced and data integrity maintained.

Alles anzeigen

And there you can find detailed information about what all the different indicators actually means. And what indicators are bad, using a warning triangle and highlighting. In my experience, once a hdd starts reporting S.M.A.R.T errors, things tend to go downhill fast. But not always. It is a good idea to monitor closely to see if things gets worse. And of course make sure one extra time that backups are good and a replacement drive is available.

If there are high costs associated with unplanned down time, it could be a good idea to schedule maintenance soon to swap the hdd before it fails at a bad time.
