I am running Windows 7 64bit.
I have two DVD drives "D" and "F" both connected by Sata to the motherboard (Asus MA78 Pro).
"D" is fine. "F" disappears! Not shown in "Computer" or "Control panel"
I have tried all the registry hacks I can find, together with all other advice from the 'web, to no avail.
If I open the case, unplug and reconnect the power cable, Win 7 will immediately recognise the drive and install the drivers. All is fine for a few days before "F" vanishes again. No alteration to the computer is done during this time.
Windows 7 is running perfectly but this is driving me mad.
Any ideas, suggestions or flashes of inspiration will be most gratefully received.
