Lost stuff..
Have they really gone or hiding ? The air was blue and unprintable. Is it possible it's done a self reset or caused by background updates?
Thanks for reading and in advance of replies.

Likely too late now, there are programs like Recuav which can be used to find files which have gone missing.

I had similar problem, turned out my twin RAID drives were failing, I managed to get stuff off the physical drive, I bought a caddie and made it into an external drive, but not found how to read data on the one RAID solid state drive which had not totally failed.

The 2 TB drive I used Chkdsk the hardest bit was to find out the windows key plus X allows you to access the command prompt. Seem to remember Chkdsk C: /r was the command used and I got it all back.
