Can I replace my existing hard drives with larger capacity drives

[atomicgamer]

I know this is from 3 years ago, but did you have any luck?  I’m currently trying to up grade my Live Duo from 3TBx2 to 4TBx2, but haven’t been able to get the system to come back to a green light…after 5 days of letting it do its thing.

Thanks
