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 Output of info: Device Identifier: disk3s1 Device Node: /dev/disk3s1 Whole: No Part of Whole: disk3 Device / Media Name: Untitled 1 Volume Name: Mounted: No File System Personality: NTFS Type (Bundle): ntfs Name (User Visible): Windows NT File System (NTFS) Partition Type: Windows_NTFS OS Can Be Installed: No Media Type: Generic Protocol: USB SMART Status: Not Supported Volume UUID: E6F4FA18-C794-465E-82A1-91A8F45C4262 Total Size: 320.0 GB (319965626368 Bytes) (exactly 624932864 512-Byte-Units) Volume Free Space: 0 B (0 Bytes) (exactly 0 512-Byte-Units) Device Block Size: 512 Bytes Read-Only Media: No Read-Only Volume: Not applicable (not mounted) Device Location: External Removable Media: No Any ideas would be appreciated.
