I have an HP 635 notebook using Win 10 and experience an usual issue with the DVD drive. I have a hp CDDVDW SN-208BB drive. After I restart Windows, the DVD drive in explorer shows as a removable drive as a result the DVD player is gone. I looked at device manager and see an additional DVD drive which is a "Hitachi HTS723225A7A364". I can remove the drive, and then prompted to restart my machine, the issue still exists. However, if I turn on computer off for about a minute the Hitachi drive is no longer shown in device manager and my dvd player works. Any ideas? I have tried to uninstall both DVD drives, check for updates.

Do you happen to have any drive virtualisation software installed? That could cause something similar to this.
