In case youi haven’t formatted yet…
Autoplay is Windows going too far. It means your computer IS recognizing the Fuze and is trying to start playing music files, showing photographs, etc. Click to close the Autoplay box, or cancel, etc. and you should see the unit.
Right-click on the Sansa folder for Properties. The second tab is Autoplay. Open it. You’ll see Music files in a box, and a list of things to do automatically. Check “Take no action” and Apply. Think you’re done? Not in Windows. There are three more choices under music files in the drop-down menu–Pictures, Video files, Mixed Content. Show each one, choose Take No Action and Apply, on to the next. Click OK and Windows shouldn’t try to Autoplay the Fuze again. If you’re lucky.
Now that you’ve dealt with Autoplay, you can right-click again on the Fuze, Properties, Tools, Error-Checking and maybe zap that bad file without formatting.
If Error-Checking doesn’t find the problem file, you will have to format.
