Drive failure to data protection to 200 hours to complete

So, I plugged in my Drobo yesterday and received a drive failure warning. Fine. I removed the drive like Drobo Dashboard said to but then figured I’d pop it back in because I dont have a replacement yet. Then data protection started and it now looks like the drive failure warning wasn’t true(?). It appears like my entire storage is now being reshuffled and protected all over again and I currently have 144 hours remaining. Yep, that is 1 week of time that I cannot unplug my laptop from the Drobo. The thing is, I don’t know if that 4th drive is still good and if my data is being protected correctly. Anyone have a clue if what is happening is actually a good thing or if Im in trouble here? Also, 144 hours is insane.
