Clip Sport 'Stuck' on 'Refreshing Your Media'

Thanks - but I have already tried this.

I am using a proper USB data cable. 

… With the cable attached - when I plug it in I never get to see the Sandisk drive - The display always goes straight to ‘Refreshong your Media’

Is there a way of bypassing this so I can mount the device on my PC? and wipe/clean the Flash memory or Upgrade the firmware.

Best Wishes
