MAC OS X Mountain Lion Ironkey Temporary Fix


For all those that are waiting on IronKey to get a fix together so you can access your IronKeys again, I have put together the steps I used to get this working.

  1. Before inserting your IronKey, Open a Terminal window
  2. Type the following command in the terminal window and note the output:
    ls -l /dev/rdisk*
  3. This should give you output similar to the following:
  4. Insert your IronKey and run the above ls command again. You should see additional /dev/rdisk* entries. In my case it was /dev/rdisk4 and /dev/rdisk4s0
  5. Using the above information, modify the following script to use your /dev/rdisk4s0 entry. Note that you will need to change the <username> to your username that you are logged in with. Then save it in your home directory as (or whatever you want to call it).

    # Updates and loads the IronKey interface
    sudo chown <username> /dev/rdisk4s0
    /Volumes/IronKey/ &
  6. Update the permissions on the script so that it can be executed.chmod +x

Now when you insert your IronKey open a terminal and execute to update the device and allow the IronKey app to access the device.

I am sure there is a way to load this script each time the IronKey is inserted. But will have a look at that later.

For those that are adventurous and do not want to put in their password each time they run the above script. Using the visudo command add the following line to the bottom of the sudoers file. If you don’t know what this file does DO NOT TRY THIS, this may screw with your system in bad ways if you get it wrong, or cause other hazardous things to happen or open security holes…

<username> ALL=(root) /usr/sbin/chown <username> /dev/rdisk4s0

I am sure there are others out there that have some ideas/input, please let us know so we can get this sorted for everyone suffering from this issue.
