Hi - did you get a solution to this issue.
I have a WD EX2 Ultra fitted with 2 Ironwolf Pro 8TB Drives. Originally it was set up for RAID 0 but then I got the red light on Drive 1. It did go off after a reboot but then came back a day or two later. I decided to switch to RAID 1 for safety and after doing so I RMA’d the hard drive back to Seagate. I fitted the replacement drive when it arrived and rebuilt the RAID (Yawn) and it worked fine for a week and then bingo - the red light came back on Drive 1. Again it goes away after a reboot.
Now I’m pretty sure the drive is OK and I think it must be a glitch with the WD’s firmware. Everything is backed up and it’s only media for personal use anyhow.
