Need help please.. over night (after some heavy copying) my new HD appeared as missing, i tried to reactivate but was unable to bring it back, tried the DOS online command within Diskpart, still no luck.. i then deleted and recreated the partition (did not format) and thought the system will bring back the partition.. maybe that was a mistake, i still did not format, but dont know what to do from here. i have some stuff like Partition Magic and R-Studio, not sure which way to go and thought of consulting some experts out there.. any help is appreciated ..
