mount reports:

Note "permissions" option was not honored, and instead "default_permissions" appears. (Also blksize=4096 is being added without my request.) Why does the "permissions" option get changed to "default_permissions"?

I've tried both ntfs and ntfs-3g mount types. They both return with a "fuseblk" mount type.

The permissions option allows each file's owner, group, and ugo_rwx permissions to be set independently. With default_permissions you can only set these one time for all files in the filesystem, and you can't individual set each file's user, group and permissions.

  Answer: no, there is not a 2nd place which provides mounting information. This is almost certainly an issue with ntfs-3g specifically. Can you please clarify whether the first invocation of mount (using fstab) is performed with root privileges / sudo or not. (This isn't as stupid as it sounds because it is specifically possible for ntfs-3g to be setuid-root).

The permissions option is ignored and automatically changed to default_permissions whenever any of the following options is also included with it:

uid, gid, umask, dmask, or fmask

To help fix this you can use user_id and group_id in place of uid and gid.

But you must not use umask, dmask or fmask with permissions.

You'll know it's working when you get the following status from mount:

Using default user mapping

---

Note that initially all files are owned by root. You might want to change them recursively to be owned by you.
