I have followed all instructions http://blog.bittorrent.com/2015/09/04/sync-wd-raspberry-pi-2/ for software install and formatting http://community.wd.com/wstd/attachments/wstd/wdlabs/26/1/Partition%20Format%20Mount%20Instructions_v02.pdf
Yet on the gui at 8888 btsync still states that the config file does not allow permission to access /mnt/data which is where my drive is mounted and confirmed via df -h command. Any assistance is much appreciated
