Basically, if your device works fine, the drive should already be installed, but if you want to check it out, follow the next steps: right-click on My Computer, select Manage and hit Device Manager from the Performance Logs and Alerts tab. In the right panel, a list of devices should appear. Select the one you're interested in. If there is a problem with its corresponding driver, it should be followed by a yellow exclamation mark. Right-click on it and select the desired action: update, uninstall or install driver.
