When I hook-up my external hard drive that contains my Time Machine backups I see the activity light on. When I run Disk Utility's Repair Disk I receive the following:
Error: Unable to unmount volume for repair.
I have tried running ps -ef | grep fsck_hfs in terminal to isolate the PID but I am not seeing the correct process. Am I running the command correctly? If not, how can I see what process is running on the drive so I can kill it?

Thank you for looking.
