I tried this just now with my drive which is the 1TB drive and I have Win7. Most of the steps are the same except I don’t see “optimize for performance” I see “Better Performance”. It worked. I can safely eject now although I got a popup regarding WD Smartware not working the first time. Now when plug in my drive, unlock it, access it successfully, I can eject it properly. Thanks! Re: “Safely Remove Hardware” won’t work on Passport Essential 750GB If you are using Windows XP/Vista, then please follow the steps below:

Right Click on Mycomputer/Computer, then click on manage.
On the Computer Management, Click on Device Manager and then select Disk Drives.
Right Click on the External drive and select properties.
On the properties screen, select ‘Policies’.
Now Click on “Optimize for Performance” and Click on OK.
You will get the screen to restart the computer, Click on Restart to make the necessary changes.
Once Windows is back, now use the Safely remove to unplug the drive. It will work.
