I am having a hard drive problem with a second HD for my wifes computer. I formated a 150GB HD from an old computer of mine (same age as my wifes computer) then pulled it out of my old machine and dropped it in hers. Her computer does not see the new HD. I looked in the device manager and it isnt listed there or under disk management. I dont think it is a jumper issue because this HD was a secondary HD in my old machine and is plugged into the secondary cable for the Mobo. I checked the BIOS to make sure that the second SATA connect was enabled and it is. Any ideas on what I can do to make this drive show up on her computer?
