However.. for some reason, the Maxtor hard drive decided to pop up after connecting it to the new enclosure again. So all of that data has been recovered from that one including all the WMF of the entire library and four of the DVD material.
The one that is clicking turned out to be a Seagate in a Maxtor skin. (I would think it would be the other way around.)
Anyway I'm grateful for all the advice and feedback.
