    cannot unmount because device is busy

    Hello,

    Code:
    HP 210 Mini
    Fedora 14 xfce
    2.6.35.11-83.fc14.x86_64
    I have inserted my handy drive. However, when I right click and select unmount I get the following message:

    Code:
    An application is preventing the volume "New Volume" from being unmounted
    So I try from the command line:

    Code:
    umount /dev/sdb1
    And I get the following message:

    Code:
    umount: /media/New Volume: device is busy.
    All I have done is copied some files to my handy drive. So I am not sure what process is keeping my handy drive busy.

    Is there any command that I can use to see what process of anything else is using the handy drive?

    Many thanks for any advice,

    Hi UK2
    you can use the command 'fuser -m /dev/sdb1' to show processes that are using the device.
    Then 'ps auxw|grep <number_of_process>' to know the name of that process.

    If you want to kill all processes that are accessing the disk use 'fuser -k /dev/sdb1'.

    I had this problem with nepomuk some time ago, maybe yours is the same...

    Is there a Nautilus window open that is displaying the files on the "handy drive"? If so, close it.
