I have this 500gb Seagate SATA hard drive that I am unable to initialize. it shows up in disk management as: not initialized & show a small circle with a red arrow pointed downward. When I try to initialize it, the virtual disk manager says: Device not ready. I tried Diskpart & did a clean on it but still wont work. Did a lot of searching on the web to no avail. Any suggestions or will I nee to chuck it ? Thanks........................
