External HDD not detecting in Mac

[sunsh007]

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.

You tried it in a different Mac.
You tried it in Windows, with no good news there, either.
Sounds like your drive has failed, so in that case, formatting will likely fail, too.

You could try W-D's software. If you have a Windows laptop, you may want to try the Data Lifeguard Diagnostic, which is downloaded from that page.
