Whenever I reboot from within Windows (either manually, or from a prompt, such as a settings change), the machine does the memory check, and the A: drive powers up..after that, it just hangs. It will not recognize either of the 2 hard drives I have.If I power down completely, or if I simply restart Windows, it works fine. I’ve tried reassigning the drives through the BIOS, and reformatting the MBR…no success.
