Hello Jmoore777,
I would first attempt using another USB cable followed by listening to the device once it is powered on, are you hearing any tapping or clicking? Does the drive spin up?
You can take a look here for steps on troubleshooting the device, run through the steps and let us know your findings.
You may very well have the remove the drive from the enclosure and use another means of accessing the data with a device such as this.
