I installed a new WD MyBook Studio 1TB drive today and discovered a new firmware upgrade was needed for Leopard.
Instructions for installation which say to connect drive via Firewire were incorrect, causing the installer to hand and requiring a call to tech support to resolve. Turned out the firmware addresses some Firewire issue and drive must be connected via USB 2.0 to load the patch.
Instructions are here: http://support.wdc.com/download/?cxml=n&pid=39&swid=60
The patch makes the buttons software obsolete and it must be uninstalled prior to running the patch. There is a new DriveManager Application which replaces it: http://support.wdc.com/download/?swid=61
The update appears to apply to most WD models so if you have one you might want to check.
