If the driver is corrupted then uninstalling the device and rebooting, so that Windows will try to install it, would be the first thing what I personally would try. But that requires to either have the appropriate drivers for the device in the Windows installation (or the installation CD) or on the CD that you might have gotten with the device. For me it would be the first (i.e Windows uses the device drivers it already has on in the Windows installation.
You can also google for the newest drivers for the device and download them prior to the uninstallation of the device. If Windows then requests the drive, you just locates them where you have saved them.
