Windows 10: Drive Unreadable?

He told me it was likely a motherboard issue and that I'd need to replace both. Is there something I can do, even if to get even some of my files back?

Hard Disk is unreadable after updates

Windows 10 Mail app: many of my unread emails are not appearing when "Unread" option is chosen

Have been using Windows 10 Mail app on my PC for some time. Suddenly this afternoon I noticed that only 4 of my 20 unread emails appear when I choose the "Unread" option. Why are the other 16 not listed anymore?

I checked the 16 missing emails and they are all still marked as "unread" so why are they not appearing when I choose the "Unread" filter?

Have tried troubleshooting and fixes supplied by Microsoft but the problem remains.

Is this something that others are experiencing? Any suggestions?
