I have an EX4100 with four Red 3TB drives (WD30EFRX) in a RAID configuration. I bout the drives in 2020. Disk 3 has failed and so I have bought two 4TB Red - one to replace the failure and the second just-in-case and as the start of an upgrade of all disks. My question is what do people advise me do with the second. Do I keep it in its box or replace one of the others? If I replace - then how do I chose which?
Ummm. I have just rerun the quick system test and it now shows no errors. But the LEDs under each drive are still RED. The RAID health shows “All RAID Volumes are active and healthy”. The Disk Status shows Drive 3 as Bad. The SMART data is:

Sorry - it was the Quick DISK test that I ran.
Interestingly - I ran the FULL disk test and all four disks passed:
| Disk1 | Passed - Full disk test completed successfully. |
|---|---|
| Disk2 | Passed - Full disk test completed successfully. |
| Disk3 | Passed - Full disk test completed successfully. |
| Disk4 | Passed - Full disk test completed successfully. |
Is there still a failure? What do I do now?
