    Arrow [Solved] Changing owner of USB

    This is a silly problem but I have not been able to find a solution.

    I have a USB Flash device that I reformatted using Gparted as ext3. The reformat was successful and the device works fine, the only problem is that the owner is "root" and I can only write to it by logging in as root. I would like to change the ownership and have been though Gparted, Policy Kit and the forums here and haven't found a way to do that.

    Any help is appreciated.

    Change the ownership of the mount point

    Code:
    chown USER:USER /path/to/mount/point
    Substitute your user name for USER. If you have subdirectories, you might need to use the -R flag with the chown.

    Re: Changing owner of USB

    Thanks for your reply. That makes sense but I am just getting errors, so I think I am not following your instructions correctly.

    The user's ID is "ruth" and the device is called "Ruth 15GM Flash"

    Here is what I typed:

    $ chown RUTH:RUTH /media?"Ruth 15GB Flash"

    and it returned:

    chown: invalid user

    I tried several variations, capitalization etc with no success. Can you perhaps give me the exact command from the info above? Thank you.

    ruth:ruth -- usernames are not uppper case; sorry for the confusion.

    Re: Changing owner of USB

    Thanks you for that - that was about the only variation I missed!

    So I typed in:

    $ chown ruth:ruth /media/"Ruth 15 GB Flash"

    and it returned:

    chown: changing ownership of '/media/Ruth 15GB Flash': Operation not permitted.

    Because "root" is the owner should this have been a sudo chown instead?

    Smile [Solved] Re: Changing owner of USB

    That worked! However it left the folders and files on the drive as still belonging to "root", so I ran it again like this:

    $sudo chown -R ruth:ruth /media/"Ruth 15 GB Flash"

    and that recursively changed the ownership of all the files on the drive.

    Thanks so much to both of you for this!
