I plugged mine into the computer, and the "H300 E:/" drive popped up, but when I click on it, it says "insert a disk drive into E" - it won't work onthe computer at all, I can't look at what's in it, and when I click properties, it says that there is no memory on the device, but when I unplug it, there are 6000+ songs on there which all work fine...very strange. Anyone know how to fix this?
