Unable to mount my external exfat disk [duplicate]

It is saying this:

Error mounting /dev/sdc2 at /media/sudheer/Untitled:
  Command-line `mount -t "exfat" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,
  iocharset=utf8,namecase=0,errors=remount-ro,umask=0077" "/dev/sdc2" 
  "/media/sudheer/Untitled"' 
exited with non-zero exit status 32: mount: unknown filesystem type 'exfat'

You get this error because the exfat filesystem is not installed in Ubuntu by default. exFAT is a proprietary and patented by Microsoft.

Since Ubuntu 13.10, this package is in the main repository. Just install exfat-fuse and exfat-utils:

sudo apt-get install exfat-fuse exfat-utils
