How to Fix - CDROM mystery lock out?

CDROM mystery lock out

On a Windows 7 PC which has run normally since January 2011, the CDROM drive has spontaneously become unavailable.  Looking in Device Manager the usual exlamation mark appears but the driver is said to be up to date and the correct one.  I checked the
SATA cables, power and signal and the device has power opening and closing in response to pressing the little button on its front.  I concluded that the Samsung CDROM drive was the culprit and have today replaced it with a new Pioneer CDROM drive only to be
confronted with the precise same problem.  I have run the hardware troubleshooter to no avail.  The only thing that I have yet to try is swapping the power and signal cables for new ones but that is very unlikely to be the source of my grief!  If power is
clearly reachjing thje drive then surely the only suspect cable is that used for the SATA  to mobo connection?

The stark message I get if I remove the drive in Conrtrol Panel and reboot is that the driver has failed to install correctly.  That contradicts the messages I get if I go for a driver update.  The message then is that the driver is the correct one.  I have
looked in Disk Management and the CDROM is simply not detected.

My PC is OK in all other respects.
What else can I try?
