I would first remove the internal drive mechanisms (isn't this a dual drive unit?) and test them the clicking sound doesn't sound promising, that's likely a drive about to go. but I've also seen several external drive enclosures with dead interface logic, meanwhile the internal drive was fine. anyhow if this is a dual drive unit, then perhaps you can at least salvage one drive and reuse in another external enclosure.
