I have a triple boot system: macOS, Windows (Fast Boot disabled), and Xubuntu. Beside the OS drive, there's a data drive formatted in NTFS.

I use ntfsusermap as mentioned in osxfuse's NTFS-3G guide to write to the drive on macOS. However, I can't write normally under Xubuntu anymore. For example:

  • touch new_file does create new_file, but it complains setting times of 'new_file': Permission denied.
  • rm new_file complains remove write-protected regular empty file 'new_file'. rm -f works.

I think this ntfsusermap is the problem, I've never touched the permission on Windows. What can I do to fix or at least debug this?

Update: getacl on the drive gives me this:

# file: .
# owner: root
# group: dialout
user::rwx
group::rwx
other::rwx

And on any file, folder inside:

# file: xxx
# owner: 501
# group: dialout
user::rwx
group::rwx
other::rwx

Update 2: My fstab line, I just copy the line in this answer:

UUID=xxxx /media/DATA ntfs rw,auto,users,exec,nls=utf8,umask=003,gid=46,uid=1000    0   0
