I get the message to disconnect all USB devices and connect only the WD drive, but the WD drive is the only one connected?

The software peopleneglected to insert a message that you were already up to date. Check this http://community.wdc.com/t5/Other-Ideas/More-useful-error-messages-in-Firmware-Updater/idi-p/80189
