NTFS Disk "failed to mount" I have an iMac running El Capitan, and an external disk formatted NTFS that will not mount on the mac.  It will mount perfectly in Windows and Ubuntu.

I'm not trying to write to it, right now I just want to read.

Here's my output of "diskutil mount disk3s1":

Volume on disk3s1 failed to mount
If the volume is damaged, try the "readOnly" option

Any ideas would be appreciated.
I was getting the above error and a suis premount dissented error. I was eventually able to mount it by with:

sudo /sbin/mount_ntfs /dev/disk3s1
