I saw the same message, along with a host of other wierd things, on a friend’s 8Gb Fuze, right before it locked up and died. I had just taken it out of the box for the first time. It couldn’t be reset in any way; the computer wouldn’t recognize it AT ALL—no matter how I tried. My friend returned it to Sears for a refund.
However, I haven’t had any problems with my 4Gb Fuze, and I’ve had it for about a year.
