I have tried all previous advice. When i go to disk management, i do not get a pop up window "Initilize disk", and this drive does not appear in the listings........I have checked and the Sata drive does not have to be changed to "a slave".......It is connected to a Sata port card in the mother board. Which was installed at the same time, and is showing as installed properly and working.........I am totally confused...Please help
