<p>The drive is a 3 month old (maybe 15 hours total use) Seagate Momentus, 320g 7200rpm. The non working adapter is a cheap one by the name of TrekStor. The working adapter is a generic KingWin unit, SKU 623603 at MicroCenter. I am looking at the Ageis NetDock to serve as a replacement enclosure for the Seagate...</p>
