I accidentally plugged my external HD to the wrong power supply. I have 2 very similar ones next to each other in my work area. Now the correct power cord won't power the HD. I realized there was a problem when I looked over at the HD and saw the red and green lights on steady and then they went out. After looking at Call For Help (G4/TechTV show) I see there are different types of HD failure, soft and hard. So I'm trying to determine which mine is. I have put it in another external case. The HD powers up and the HD gets hot, I can here it "running" but the drive is not being recognized in My Computer, nor is there any "activity" (light blinking showing something is going on). I can "add" it using Add Hardware and then "remove" using the Safely Remove Hardware function. When I go into Device Manager and click on the drive (which is showing up with an incorrect name) and go to the Volume tab and click on "Populate" it shows as Unreadable. Please tell me the data is still there and can somehow be accessed? Any ideas?
