I have an adapter that can read ide and sata HD's. When the drive is good it lights up green and when its bad it lights up red. I have used the adapter already to read about 10 other HD's with no problem. When I got to the hitachi HD it lights up green but I can't see what is on it or even format. The drive doesn't show up when I do fdisk -l, use testdisk, or use disk management in windows. I'm guessing it has something to do with a master/slave issue. There is a big chart on the HD but I have no clue how I should set it.
