Help! All data in mybook live gone and owner password unknown

Same issue, U.S. here. Getting an error using any of my mapped drives, and my admin password is not working. So frustrating.

I went through different support sites, enabling SMB1, etc. but nothing has fixed it. I don’t know how to tell if it was factory reset or anything. I saw a bunch of articles about resetting the admin password by doing a restore (without losing the data), but I’m wary of whether that will actually help, and I’m not all that tech savvy.

I hope someone from WD can help. I know I have a very old device, but it has been mostly reliable all these years…
