Occasionally, clicking the "Lock Drive" button cannot lock your device, and the message, "Your IronKey drive is still running an onboard application" appears, preventing you from safely removing your device from your computer. Your anti-virus, or some other application, might be accessing the Secure Files volume and preventing it from being locked. Try closing all other applications, and then see if you can lock it. Sometimes the Windows operating system opens handles on the Secure Files volume and prevents it from being locked. For example, this can occur when saving an email attachment from Outlook to your Secure Files volume. Here are some things you can do to discover what is accessing your device.
Try using the "chkdsk" utility to force the release of access to your Secure Volume. Here is an example using Windows XP/Vista/W7:

  1. Unlock your IronKey device.
  2. Open "My Computer", and remember the drive letter for the IronKey Secure Files volume. If you are not sure which one this is, look for the IronKey Launcher, and the IronKey Secure Files volume is likely to be the next drive letter in sequence to the IronKey Launcher.
  3. Click the Windows "Start" button, and then click "Run".
  4. Type "cmd" to open a command prompt window, and press "Enter".
  5. Type "chkdsk" and then the IronKey Secure Files volume drive letter, and then "/r" (For example, if the IronKey Secure Files volume drive letter is G, enter: "chkdsk g: /r ")
  6. When prompted to force a dismount on this volume, type "'y" and press "Enter". This will force a dismounting of all applications accessing the Secure Files volume. You should then be able to use the "Lock Drive" button normally.

If this didn't work or if you want to find out what is causing the issue, a third-party utility called "Unlocker" might help discover what is accessing the Secure Files volume. This utility adds a context-sensitive option to Windows Explorer that will look for open handles on the drive:

Other useful utilities are Process Monitor and Process Explorer. These are more robust applications with many more features, but they can be used to locate applications running on your system:
If you have shut down all applications on your computer and are still unable to lock your device, you can use the Windows Task Manager to close the IronKey Control Panel:

  1. Press "Ctrl+Shift+Esc" to open Windows Task Manager.
  2. Click the "Processes" tab.
  3. Right-click the "IronKey.exe" process, and then click "End Process Tree". Your Control Panel should close along with all the processes that it initiated. Now, try launching the IronKey Control Panel manually (from the IronKey CD Unlocker volume) and then click the "Lock Drive" button. If this doesn't work, you can use the Task Manager to kill the "IronKey.exe" process and then use the Windows "Safely Remove Hardware" utility to eject the device.

Other techniques you can try are to:

  • Right click on the IronKey icon in the Tool Bar and select Lock IronKey.
  • Use the Safely Remove Hardware and Eject Media icon in the Tool Tray and select the IronKey Secure Files.
  • Use the Safely Remove Hardware and Eject Media icon in the Tool Tray and select the IronKey Unlocker.
  • Use Windows Explorer and right click on the IronKey Secure Files and select Eject.
  • Use Windows Explorer and right click on the IronKey Unlocker and select Eject.
  • If you get the Control Panel to stop responding, then the IronKey is locked. Click on the unresponsive Control Panel and select Close the program, then Windows will look for a solution and click Cancel which will close the Control Panel window and complete the locking process.
