Factory reset time?

Hi, I know this has been mentioned before but I’ve done a full factory reset on my 6Tb single bay and I’m now on day8… I’m happy to wait if you guys think this is normal but I have no idea if it is really.

I would power off and power back on, usally shouldnt take that long, did you factory reset from dashboard or reset button?

Yes I did it from the dashboard. I’m just a bit concerned that people are saying that it can damage the the drive if I power off while it’s formatting?
