If you just rund “chmod 777” on that drive it will set these permissions only for that folder, not for subfolders or files (afaik) within this folder. By setting it as recursive, it will apply permissions to every single file and folder in any subfolder.
So if you can confirm you are only using the command "chmod 777” then that is your issue. You’d need to add something like -R or -r (look it up first, can make a difference and I don’t remember…) to the command.











You still didn’t really answer how you are running chmod and there’s two users here already telling you it could solve the issue that you need to run it recursively.
From your answer I can assume you are not doing that and it is easy to just test it, so why don’t you give it a try and if it doesn’t work then there is a whole different issue than setting permissions.
