I found with these Seagate drives with the snap tabs are really easy to open, just get a pick or credit card in 1 corner and then work round the whole outside edge and you’ll hear the popping of the tabs as you go past them. Then it should be easy enough eventually to get enough leverage to lift the cover off and even though most of the tabs will be broken most shouldn’t be at the point where they’re unusable so it should be possible to put the cover back on if you so chose to to re-use the hub.
