@paulb7873: If you want something working without any more effort, exchange the drive. Ya, different people prefer basic Green, AV-GP, Red, or Purple, for different reasons. What kind of Roamio do you have?
I do find the original question interesting. Should the WD MyBook be a supported drive for this? The only advantage I can think of is it's easy to find in retail stores, and often goes on sale.
The issue appears to be that drive is restricted to be a bit smaller than standard 4TB drives, and the configuration seems to have removed the HPA ATA commands as well, which is normally used to fix it. The options are to have a different image for that sector count, or see if a DCO reset will remove those customizations. If the DCO reset does turn out to work, the drive would no longer work if put back into the case housing.
