I want bind some folders in my Home directory with some folders in a NTFS partition. Will mounting the NTFS partition with only the defaults parameter affect my read/write access?

Default mount options are:

rw,suid,dev,exec,auto,nouser,async

This means that by using defaults in fstab the drive will be:

  • rw: read-write
  • suid: set-user-identifier or set-group-identifier bits take effect
  • dev: interpret character or block special devices
  • exec: permit execution of binaries
  • auto: auto-mount or allow mount -a
  • nouser: only root is allowed to mount
  • async: I/O to the filesystem should be done asynchronously

These options can be adapted to personal needs. All possible options are listed in the mount manpage.

For mounting an NTFS filesystem you may want to add the options: uid=0,gid=46,umask=007,nls=utf8.

This would be an example fstab entry for NTFS-filesystem using LABEL rather than UUID where all users are allowed to mount:

LABEL="NTFS_Disk"   /media/windows   ntfs  umask=007,gid=46,uid=0,nls=utf8,noauto,users   0       0

Mounting a partition with defaults parameter will give all users read/write access. As quoted from Swerdna's openSUSE mounting tutorial:

To mount your NTFS partition permanently, add your version of the following line into the file system table, fstab. [and leave the last line in the file as a blank line.] Recommended option for world-writeable mount:

/dev/sdb1    /path_to/mount_point    ntfs-3g    defaults    0 0

When you reboot, the partion will mount into the folder /path_to/mount_point with permissions drwxrwxrwx, i.e with read/write access for everybody, in the style of Microsoft's insecure filesystems.

The word "bind" appears in the title, but appears not to be addressed on this page. I fell upon a configuration which seems to work (add to /etc/fstab): 

# <file system>           <mount point>             <type>     <options>                                <dump>  <pass>
UUID=3030BD846F74E514     /media/iam/ntfspartition  ntfs-3g    uid=1000,gid=1000,dmask=022,fmask=133    0       0
/media/iam/ntfspartition  /e                        ntfs-3g    bind                                     0       0

To find UUID, compare 

ls -l /dev/disk/by-id
ls -l /dev/disk/by-label
ls -l /dev/disk/by-uuid

For uid, use echo $UID.

I'm very new to minding my permissions, users, groups, mounting and binding, and other factors, so if anyone has comments, please advise.
