WD passport - cannot view the files or folders

All I see is archive_db

this happend before - thoughy files were gone. then when I connected a few weeks later, magically they were there again… Now they are gone again!

Properties shows that 30% of space is full - so files are still there… so how can I see my files???

FYI - I am using Windows

Try enabling Show Hidden Files and see if that helps.
