Unable to change Label on My Passport Studio

I am uable to change the Label on My Passport Studio.

The drive is connected by USB to my Mac Pro running OSX Snow Leopard.

Under settings in WD Smartware, the Set Up Drive button for My Passport Studio can not be clicked to get the optons. It is showing in a light blue colour.

Light-blue on drive settings means Smartware is not fully recognizing the drive, the backup and retrieve tabs should be unavailable as well. Check the cable, the connection and that the drive is not locked and try again.
