To get your player to be seen as a drive, simply go to the USB setting under System Settings and switch to MSC (rather than MTP or Auto) mode.
Note: best to transfer evrything you want on your Clip under one USB mode and not have a mix, so that your computer will be able to see everything on your Clip at one time (your computer can only see the files that were put on the Clip in the same USB mode that the player then is connected to you computer under). If need be, to fix things, transfer all your files back to your computer (under each of MSC and MTP modes), delete the content files on your player, and then transfer everything back to the Clip under the USB mode you’ll be using.
In disconnecting, I always use the Safely Remove Device utility–a good habit to adopt, for safety’s sake, it seems to me. But at least under some Windows versions, you can turn off USB caching so that the risk of corruption is lessened even if you just yank.
