Reformatted and now data protection in progress

Hi everyone,
I just reformatted my 4bay Gen 3 because I wanted to start from scratch. It reformatted fine, but it says it is going to take 22 hours for the data protection to finish. Does this sound right? I thought it only needed to do the data protection was when you swapped or added a drive. Sorry I haven’t reformatted a drobo in years and can’t remember. Any help would be appreciated!

I have found it will take time, but it usually ends up going faster than indicated.
