I have a NSA-220 with 2 hard disks raid 1.
In Storage -> Internal Volume i have : Status: Recovering:0%, Volume:mirror_1, Disk Configuration : Data Protection (RAID1), Disks
If I press scan the second's hdd Led turns red and a message says that i have to replace hdd.
I have bought a new one with same disk space to replace it. If i shutdown NSA-220 and replace the faulty harddisk and power on, go to Admin -> Storage, i can't see any internal volume.
If i put again the faulty hdd (after i shutdown nsa, replace and power on) I can see the raid configuration?
Is it something different that I have to do or do i lose data?
Perhaps i have to change hdd while the nsa works?
