9 digit code?

Hello am new to this site and am a wee bit confused to say the least.

Have bought 2 4TB Mybook external hard drives. Both of which is immediately seen in both Adobe Bridge and Windows explorer. Brilliant!

I have created an account and verified it and all is well at the Find Device Screen.
Clicking on the find my device I get the 9 digit code request and I am simply unable to find this code?

Looked on the bottom of the disk at the sticker there is no padlock symbol just serial numbers.

Any help?

@IanJones If you own two My Books then you probable want to check in the proper sub-forum for those.
