After removing the D4 diode from the PCB, my hard drive now powers on.
However…although my computer (Windows 7) detects a USB device being plugged in…no icon appears (ex. E: drive) under ‘My Computer’ which would indicate the hard drive is being detected.
The hard drive is a 1.0 TB WD Caviar Green. I’m using the original PCB with only the D4 diode pulled off.
Here is a pick of the PCB before I pulled off the D4 diode?
