What is your power supply voltage? You can check the fuse by removing the cover; it is held in by tension and can be removed by prying it apart. The fuse will look like a green 1/4W resistor.
If you like you can send the drive back here for evaluation and we can look at it. All evaluations and repairs are performed free of charge provided everything is fixable, which it generally is. Just go to our website and fill out the form located here in PDF format and send it with the drive to the address listed at the top.
