I replaced my original HDD with a 128GB SSD. I installed the original HDD in the slot for my DVD drive. Everything works OK except that when I put the machine in sleep mode (close the lid on the laptop) and then open the system I get the following error message: " Probelm Ejecting ST9500420AS, This Device is currently in use. Close any programs or windows that might be using the device and try again". I click on OK and everything works fine. Does anyone know why I'm getting this error message and what I can do to keep it from popping up?
