Hi,

I recently had a DD down on my F4-220. My storage was RAID1 with 2 Disk of 3 TB each, one of them died (HDD1)

I have followed the above procedure smoothly.,

However I have no indicator of the new disk is currently syncing or repairing. Looking on the forum or internet, it seems usually the process takes several hours and people can tell that it is ongoing (orange led?)

In my case it was a matter if seconds to see the new disk in the RAID1 storage, green status. It looks a little bit too fast and smooth :D

Could you tell if I have a mean to double check everything is fine and over for the disk replacement?
