Trouble creating new folders on external disks

I have a macro that creates a folder in a given path and then moves the selected file there.

It works just fine on one of my mounted volumes.

However, the exact same macro fails when I try it on a mounted Hard Drive, even though the destination folder has the exact same permissions as the one that works well. If I try to create the folder using a shell script I get "Permission denied". I get a similar permission error if I try to use the "Create New Folder" action.

Things work fine if I reproduce all the steps myself in bash (even without root access).

Any ideas on what could be going on here? Sounds like a privilege issue at execution but then I don't understand why it works great for the other mounted volume.

Thanks!

Bump - I am running into this issue. Did you find a solution in the end Orsini?
