NTFS Partition Doesn't Allow Programs To Access It [SOLVED]

Hello all,

First of all, I have finally returned to Arch after several years of using Linux Mint. It feels good to be back in a bloatware-free environment, and I'm enjoying my 1 second boot times! Unfortunately, this hiatus has caused me to lose much of my former Linux knowledge base.

My System:

The Situation: I have a separate hard drive formatted to NTFS, which I use for my file storage on all of my OSes (I have 4 right now, including Windows 8).

The problem: Despite configuring the mountpoint (/media/aaron/data) to mount under my user, aaron, and the 'all' group, other applications do not have any access to the /media/aaron/data directory. Because of the fact that it is NTFS, and I am multibooting with Win8, I cannot simply chown the directory and subdirectories to my name. Instead, I had to amend the /etc/fstab to mount the directory under my user and group, which is where I believe my problem is.

Background: I have searched for hours on the internet, including the Arch forums to find a solution and the best I have found is a post here (answer #1) which at least allows me to access the directory through the file manager (Dolphin). I first noticed the problem when trying to download a torrent file using ktorrent. Ktorrent spat out the following message:

Cannot create /media/aaron/data/Downloads/wattOS-R8-32bit-mate.iso: Permission denied

Now, I think I have isolated the cause, however I have no idea how to fix it. I believe the cause is that only owner has permission to view and modify content. Group has permission only to view content. Other has no permission whatsoever. I believe that I need to somehow allow all of the users to have read and write privileges. It would be a simple chown, if it weren't for the fact that the FS is NTFS. I need some amendment to my fstab that will achieve this result, but I have a limited understanding of the various fstab options and masks.

My fstab file reads as follows:

#
# /etc/fstab: static file system information
#
# <file system> <dir>   <type>  <options>       <dump>  <pass>
# /dev/sda5
UUID=b1b2ca8c-e7fc-42a2-aabb-a2c3208c2a65       /               ext4            rw,relatime,data=ordered        0 1

# /dev/sdb3
UUID=7381274f-2aea-4960-a45e-4fe2c7afac9f       none            swap            defaults        0 0

# /dev/sdb1 DATA on /media/aaron/data
UUID=B64C82184C81D391                           /media/aaron/data     ntfs       uid=1000,gid=100,dmask=027,fmask=137     0  2

it is /dev/sdb1 that I am configuring, and the options shown above are what allow me to access the directory using my non-privileged account.

I am sure I have probably forgot something, forgive me, it has been quite a long time now! Thank you all in advance, I appreciate anyone who takes the time to give this a wee bit of thought!

Let me know what information you require, and I will see it delivered promptly,

HPG

UPDATE:

I installed the package ntfs-3g to my system, as per the Arch Wiki instructions, and then set the fstab options as follows:

UUID=B64C82184C81D391                           /media/aaron/data     ntfs-3g       uid=aaron,gid=users     0  0

Just setting the uid and the gid alone allows permissions to be granted to all groups, so this is obviously not a solution for a multiuser system. As for a single user setup - it is perfect.

cheers,

HPG
