Is there a way to find what applications are running on an external hard drive?

    Sometimes a hard drive will not "unmount" because there are applications being run from it.

    Is there a way to find out what those applications are?

    It may not be an application per say running on the hard drive...

    I have noticed if I had a file open from an external drive, closed it and the program that opened it was still running, the computer would not let me unmount the drive...

    Try quitting all applications and then try to unmount the drive.

    Then again, sometimes you just have to shut it down to unmount...

    You can open Activity Monitor, click on processes, click Inspect, click "Open Files and Ports," and that list will have everything that the program is accessing. If whatever is being accessed is on the external HDD by whatever program, closing that program should allow you to unmount the external HDD.
