Firmware upgrade: Drive in use

I’m trying to update the firmware for a Mybook Essential 1TB drive, but no matter what I turn off, the software constantly tells me that my drive is in use. How do I make it work?


de-install the smartware program.

That doesn’t work, unfortunately. It’s like the drive is using itself so it can’t update itself. It’s probably because it doesn’t pass its self test. One more dud WD drive. I’m never buying from them again.
