A few days ago my 2TB seagate expansion desk hardrive started to make a grinding and beeping noise. so i moved everything off it and did a full format hoping that the problem is bad sectors, but this hardrive has very sensitive ports and i kept accidentally bumping them during the format. the first time the drive was fine and i restarted the format bu the second time my computer wouldn't recognise the drive. everytime i plugged in the hardrive it would make the sound of it being plugged in then a minute later it would play the sound of it being unplugged when it wasn't. i have checked device manager but it isnt there and i have tried to partition it in disk managment but it isn't there.
