Well there are no zombie and "R" under "S" indicates it is running. 

Not sure if you'd run into this situation if you issue an unmount prior to the transfer being complete to the USB-HD.  Either way, if you can't kill with a "kill -9" then probably your only recourse is to reboot.  And then don't trust the data written to the drive.
