I am trying to replce the two existing 1TB drives with 2 new un-formatted 4TB Seagate drives in the TwinStore.

After the new drives been placed in the TwinStore, it is beeping and it is being formatted. The problem is that it is still beeping after 100 Mins; I assume the system is experiencing a problem formatting the new drives.

What should I do now? Turn it off and try again or else?

Anyone could offer some advise, please.

Happy Listening
