I have a 500GB SATA drive connected via a USB to my Pi 2. I can read data off it fine, but I can't write to it. It is formatted as NTFS. On my desktop, it is write-able, but not on Raspbian.

Set ownership when you mount the drive. For example if your drive that you want to mount is /dev/sda1:

sudo mount -t ntfs-3g -o uid=pi,gid=pi /dev/sda1 /media/USBDRIVE/

or if later you want to change permissions of files on the drive after mount, try to add a line to /etc/fstab something like this:

/dev/sda1 /media/USBDRIVE ntfs-3g auto,users,permissions 0 0

Note that ntfs-3g is a built-in package in Raspbian Jessie (but Not Jessie Lite), if you are using older distribution you need to install it before mount (sudo apt-get install ntfs-3g). You can check easily that this package has already installed: dpkg -l | grep ntfs-3g

I just wanted to share my experience on using the current version of ntfs-3g installed with apt-get install ntfs-3g (version 1:2014.2.15AR.2-1+deb8u2). I was getting "Input/output error" using that version. It seems to be a known error: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=774330.

You can downgrade the ntfs-3g version from the 2014 release to the 2012 release but I decided to run the latest release. So, I did apt-get remove ntfs-3g and then I built the 2016 release from source using the oficial docs: http://www.tuxera.com/community/open-source-ntfs-3g/

tl;dr

  1. Download the stable source release (in my cases 2016.2.22)
  2. Run ./configure
  3. make
  4. sudo make install
  5. Restart
  6. Done. You can use it like mount -t ntfs-3g /dev/sda1 /mnt/windows
