You need to go to the Lenova web site and download and install the most up to date drivers for your Drive. It is possible to go into System manager and uninstall the device, then reboot and have it reload the device using auto detect. If that doesn't work install the New Drivers you download. If neither of these fixes the problem you may have a drive that has gone bad. You should check with the manufacturer to see if it is a warranty repair. Otherwise you will need to buy the device and replace it. Good Luck
