I have a 500g HDD from my Asus laptop that will not show up when I slave it to my hard drive adapter kit. Does anyone know if this is a "feature" of the Windows 8 os or is it due to a hard ware malfunction on the drive itself (I can't put it back in the laptop and HDD adapter kit reads other drives) kit? It looks like the drive is made by HGST? It's slim, sata and was made in 2013. Any feedback on this would help. Thanks
