I have a Ex4100 with 4x3TB WDRed drives. recently I updated the FW, and also had a power failure. As a safeguard I did a disk test that ended with no errors (took almost a day) and after that the EX4100 is now always on, furiously grinding the disks and never goes to sleep. Recently I did a reboot and it’s been uptime for 3 days… always working on the disks.
I have no backups, no app running, no scheduled activity. I turned off all devices, even discoinnected the network and the disks just keep going on…
Everything looks solid, no errors, no status changes, auto sleep is on, no suspicious activity.
What could be making the WD behave like this?
