I have four external drives attached to my iMac. Three Western Digitals (one is my Time Machine backup), and two others for general storage. My fourth is a Seagate 2TB, also for general storage (it holds my e-books, work video tutorials, and YouTube videos I have saved). When I access my WD drives remotely (over wifi), all folders and their contents appear, and quick look works without problem. Not so with my Seagate. When I try to view the contents of any folder remotely on the Seagate, it shows 0 items (but the drive shows space used correctly - out of 2TB, there is 924GB used). When I go to my iMac I can see everything no problem, it is only over wifi that it says there are 0 items in the folders. Does anyone know why this is happening? It is only since I upgraded to ML.
