I have a WD Sharespace 4TB NAS with 4 x 1TB in RAID-5 with WD Green Hard Disks.
Recently i saw a blinking orange led. I’ve logged in web interface and went to**
**disk manager.There I can see all 4 disks in Good Status.HDD4 reports Unassigned.
Next to it are 2 options 1. Safely remove disk 2. Clean Disk
Should I proceed with one of these options to rebuid the array or should I do it through ssh with mdadm?
