Firmware will not upgrade - says the drive is being used

Hi there

I just connected my My Book Essential for the first time and so I’m trying to upgrade my firmware. I download the files from the WD-site, unzip and start the installation. However, after the step where you click “continue updating” (or whatever that button says in english (my installation is in swedish)), there’s a message saying that my drive is being used and that I have to close all programs and try again. I have tried closing like everything, but the process just keeps repeating itself.

Anyone got an idea what might cause this?

Apparently there is an application trying to access the drive. I would recommend you to reset the computer and then click here for the instructions to update the firmware on My Book Essential. If the issue repeats, try doing this steps on a different computer.
