Passing SMART test but not EXTENDED on DLGDIAG + Fail to repair (Error 08)

Hello everyone!

Lately I got errors in checking torrent files whenever I closed and reopened utorrent, googling it I found it could’ve been caused by a damaged hard drive, so I got to find dlgdiag, and ran it.

SS of SMART data

What I need to know is if I have to worry about health of my hard disk or if it’s an issue in dlgdiag that could’ve been caused by any other factor. Or in case, how to repair.

Ty all in advance
