Cryptsetup |

If you are running Linux OS like Ubuntu and you recently try to mount your encrypted USB hardrive, then you probably got error message "Unable to mount." If so, then you probably don't have cryptsetup utility installed on your system. It is needed to encrypt and decrypt device.
To install the cryptsetup, open terminal window and enter the following command as you see it exactly:
sudo apt-get install cryptsetup
Once it successfully installs, then you should be able to mount your USB hardrive after entering your passphrase using GUI or terminal.
