My WD 2TB HDD suddenly ejected automatically and a message of improper eject came up. I connected the hdd again but it did not detect. It was not showing in disk utility either. I checked it in another macbook but same issue. Then I connected in windows laptop and it got detected in USB 2.0 port but was not showing up in windows explorer. I checked in disk management and tried to open it but was not opening. Right clicking was giving me only two options : delete volume and help. All other options were greyed out. Can anyone please help here ? I don't want to format the hdd.
