backup disc disapeared?

I was on Safari, when I suddenly got the message that my back up disc had ejected. I did not do this, I wasn't anywhere near the desktop. I cut the computer off and rebooted, checking all my connections and the light comes on on my back-up disc, but no matter what USB port I put it in, my iMac wont recognize it. I check my system and it doesn't show up, just my blue tooth an my keyboard.

I am using a - WD my pasport portable HD it us a USB 3.0 and 2.0 compatible

I have tried everything I know and it just won't appear on my desktop.

All help appreciated.

iMac, OS X Mavericks (10.9.2)

If other USB devices are working, then the WD Passport my have failed.

If no USB devices are working, disconnect everything and reset your iMac's SMC.

Intel-based Macs: Resetting the System Management Controller (SMC)

1. Shut down the computer.

2. Unplug the computer's power cord.

3. Wait fifteen seconds.

4. Attach the computer's power cord.

5. Wait five seconds, then press the power button to turn on the computer.

Additionally if you are using that drive for Time Machine for backups, it might be a good idea to purchase a more rugged External Hard Drive.
