Permissions for ntfs and vfat file systems must be set with the
dmask controls permissions for directories,
fmask controls permissions for files, and
umask controls both. Since these options set masks, they should be the complement of the permissions you want. For example, rwx for the owner and rx for others is 022 rather than 755.
To set the owner, use the
gid options for user and group, respectively. You can find your UID with the command
id -u. To find your GID, use
id -g. These values are both usually 1000.
A common set of mount options for ntfs is
uid=1000,gid=1000,dmask=027,fmask=137. This sets you as the owner of the drive, and sets the permissions to
Here are two lines from my /etc/fstab working
UUID=EEA2B69CA2B668AB /WIN_C ntfs-3g defaults,nls=utf8,umask=000,dmask=027,fmask=137,uid=1000,gid=1000,windows_names 0 0
UUID=65AEC0E830EA0497 /WIN_D ntfs-3g rw 0 0
If you get no visible error after rebooting and partitions stay readonly or you get an error similar to:

This is because Windows 8 and 10 offer a "Fast Startup" option that depends on a "non-complete" shutdown. You can disable fast startup by following these steps under "Power Options".
