After unboxing, I created two partitions (OS X extended and FAT). After an hour, the partitions could not be accessed anymore. Thus, I tried to delete them using wd drive utilities which does not work either (neither on a mac nor on a PC). Error message: "Das Laufwerk konnte nicht gelöscht werden.“ (german for drive could not be deleted.)
