I haven't heard of that specific issue as common so I don't know where you got that idea. Be very careful about how you go about trying to update the fw. You are probably not reinstalling the FW correctly since you shouldn't be able to see the drive when plugging into your PC until you've begun the process.
Reset (pin hole on top). Hold the up button continuously while connecting to your PC and until you hear the device recognition beep from your PC. It should NOT show up under my computer or you've done it wrong and start over. After it's in but not showing as a drive, open the updater it will find it. It will than show up as a drive. Do not start the updater. Now that you can see the RoCoo drive, format it in 'my computer' instead of just wiping it in the updater. When finished, start the updater without any options and when complete eject like any other USB device.
