You might need to import the disk...are you logged in as an super-user / administrator?


In XP bring up Administrative Tools (in Start Menu/Control Panel IIRC) and open the Computer Management applet. In the window that opens up find Storage -> Disk Management. Then find whatever looks to be your n-gage and see if you can import the disk.


It may or may not work. But it should tell you if the computer can tell there is a disk attached but for some reason or another doesn't feel like importing it.
