Is it possible to reverse the factory restore option?

I was trying to reset the device cause was having some minor problems and before i realized what i hit i x’d out and rebooted. but unfortunately i still erased 280gb. Is this reversible?

Maybe you should try contacting WD’s Technical Support about this. You can do so either by phone or email.
