Why I cannot change the ownership on mounting ntfs drive?

I give uid=1000,gid=1000, etc in my /etc/fstab file, but found it is not working. So I'm testing it out on command line:

root@host:~# mount | grep /mnt/tmp1 | wc
      0       0       0

root@host:~# mount -o uid=1000 /dev/nvme0n1p4 /mnt/tmp1/


root@host:~# mount | grep /mnt/tmp1
/dev/nvme0n1p4 on /mnt/tmp1 type fuseblk (rw,relatime,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096)


root@host:~# umount /mnt/tmp1


root@host:~# mount -o user_id=1000 /dev/nvme0n1p4 /mnt/tmp1/


root@host:~# mount | grep /mnt/tmp1
/dev/nvme0n1p4 on /mnt/tmp1 type fuseblk (rw,relatime,user_id=0,group_id=0,allow_other,blksize=4096)

Changing the ownership is absolutely possible. See this page: Mount NTFS partition at startup, with non-root user as owner and Change owner of internal hard drive partition from root to user

Basically, add uid=1000,gid=1000,permissions and possibly play with umask=000,nls=iso8859-1,users. Use mount -a to test without rebooting.

NTFS is simply not capable of POSIX ownership and permissions, which is how permissions and ownership is handled in Ubuntu.

If you have a task that needs to store data on a file system with POSIX ownership or permissions, you cannot use a NTFS file system.
