Use SSH or samba. pretty sure windows cant read linux file system.
else if you want to take SD card and just use it own your pc put ubuntu on a flash drive and use that whenever you want to make change using physical media
thanks for your reply, but this unfortunately does not resolve the issue.
In order to be able to read the SD card when plugging it into my windows, I would need this overlay activated because otherwise, as you say correctly, it is not readable by Windoofs.
So per default I access it via ssh anyways, but you know. The day will come I might need to access the physical card on Windows e.g. to recover data, and that does not work with the default settings for the file system mentioned above.
