Installing a new disk in a blue ring device

I have the need for more storage, so I’ve bought a 2Tb WD USB drive. Thinking about it, I thought that the 21Tb would be better on my network, and the MBWE 1Tb would be better as USB, so I swapped them.

However it obviously isn’t that easy. The MBWE is not joining the network.

I’ve found info elsewhere about “rescuing” the new drive but that’s all Linux, and I’m a proficient XP user. Is there a similar process for XP?
