FAQ

how to check SSD health on Windows?

SMART data exists on every modern drive but Windows buries it, so people find problems after a crash, not before. smartscope reads the same data and translates it into a three-level verdict with a temperature history that shows drives trending hot or worn. It is a 100 MB portable exe, MIT, no ads and fully offline with SHA-256 releases.
