My cloud user name abd password issu

Hi I’ve just joined this group so apologies if I get things wrong. It’s a long shot. I have an older my cloud 6tb duo that I’ve not used for along time as I replaced it with a newer My home cloud system, which is working just fine.

I’d like to start using the older my cloud machine again to store photos and music, but I can’t access the drive as it is registered on an old, no longer used email address, I can remember the user name nor the password. I’m happy to reformat the drive and start again, but my Mac disc utility says I need disc admin permissions, which of course I don’t have, any suggestions would be very welcome.
