Also try looking to see if you can see it under disk management, maybe it needs a HD letter assigned, for this right click on my computer and click on manage then you'll see disk management on the left.
Also you might want to check your BIOS to see if it sees it in there.
On a Mac....
tried 3 different USB cables
Can I open it and install the HDD as say, an internal drive on my PC?
