My HP Pavilion with Windows 7 is not seeing my Samsung TS-H653L CD/DVD reader/writer. When checking my Device Manager for this unit, it shows the following message: "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)." I tried to "update this driver" but the answer is that "this driver is up to date". Can't find any website with Samsung TS-H653L driver updates. Tried removing the driver and rebooting but same thing happens. Any ideas are appreciated.
