"Missing" files, maybe messed up indexing

[MorbidNature]

So i recently upgraded my PC (new CPU, new MB etc, you get the point...)

I did a fresh OS install install on my NVME but left my other drives alone.

 

Last night I went into one of my storage drives and found out that whole massive folders were missing (Pictures, about 1.5 Tera).

Now the drives shows  it's full but the files themselves aren't "there"

The hard drive is a WD red 3TB so its rather unlikely it failed (it's 3 years old without too much wear), I think its an "indexing" issue somewhere along the new install the files index got screwed up ,which is still showing the same size.

Now I have backups for all the data that was stored there but it would be nice to figure out and recover what happen.

 

If anyone has any ideas i'd love to hear them

Use Windirstat and see what is shown as eating all that space up.

I know exactly what's eating that space... my files... I just cant access them for some reason
