With the ntfs3 linux module, some, but not all, directories of the ntfs partition do not have permissions that are consistent with dmask set in /etc/fstab. Based on a small set, the files permissions are consistent with the fmask setting. More specifically, does, for example, dr-xr-x--- Users/Default/Downloads Consistent with dmask 0027 from /etc/fstab? Mount point omitted by submitter. The issue is seen with 5.16rc6-1 (mainline), and with with 5.15.10-arch1-1 (by the archlinux distribution). On the surface, it could be that https://unix.stackexchange.com/questions/678880/how-can-i-mass-set-the-permissions-of-existing-files-in-the-new-ntfs3-driver is related. I have no relation to the person who wrote that stackexchange report. While writing this message, I have also noticed links such as 'Users/myuser/My Documents' -> C:/Users/myuser/Documents Should a C:/ mount point appear in a unix ls output? Mount point omitted by submitter. Do let me know if I can assist further in solving the issue. Thank you for your work. -- u34
