I have a dual-boot with Linux (Manjaro) and Windows installed on two separate SSDs, plus I have a shared ex-fat HDD which contains documents and the like.
Problem is, very often, when I'm on Linux and I create or copy a file or folder on the HDD, then I cannot see it from Windows. If I switch back to Linux the file is still there. Sometimes it seems that it becomes visible also on Windows if I create a new file in the same location with touch for example, but I'm not sure about this.
The opposite works correctly, i.e. if I create a file from Windows, I can see it from Linux too.
Any idea why this happens?
