I just tried CD/DVD Drive Locker and it worked on Windows 7 Home Premium 64 bit.
If you have small children in your
family, then you are probably familiar
with the situation in which straight
after they learn to move around
independently, they begin to touch
everything that they came across.
In particular, children like to open
and close the CD/DVD drive on the
computer, and press the Reset button.
The CD/DVD Drive Locker helps to temporary turn the CD/DVD ROM drive off, and so pressing on the CD/DVD drive's buttons doesn't lead to the CD/DVD drive being ejected.
