Hi,
If formatting and reinstalling does not resolve the issue, then you have a
hardware problem. Either the drive, the controller cable, or the motherboard
socket is bad. Reseating may help.
It is not unusual to have two listings of controller cables in Device
Manager if more than one cable is in use on the system. There would be one
listing for each. It'd only be an issue if the controller driver wasn't
loading properly, and that'd be indicated by a !bang in front of the device.

Thank you for responding however your assumption that one or more hardware
items may have gone bad in my case is incorrect. If a hardware items had gone
bad I would NOT have been able to reinstall the OS. Therefore there may be a
driver conflict; if you have the time to research in other forums there will
be numerous listings indicating problems with DVD/CD-ROM and SATA drives that
have stopped responding.

I failed to mention when I uninstall one of the listed storage controller
drivers the DVD/CD-ROM drive will become active and stay operational until a
restart.
