Weird.
Dell OpenManage does the monitoring and emails me an alert. In this
case the disk seems to function fine, so I wonder if OpenManage is just
trigger happy with the failure prediction.

I'm more impressed that you're actually getting a report predicting
that the drive is failing. I have never ever had a raid controller
report a disk may be failing. They just go straight from working to
failed. Usually failing into a high latency state, where they still
work, just really really slowly, so the raid doesn't take it offline.

I've got a somewhat old Dell Poweredge with a PERC H700 RAID

About a year ago SMART predicted a failure on disk 4, so I replaced
it. A few weeks ago SMART predicted a failure on disk 4, so I
replaced it. Today SMART predicts a failure on disk 4.
On the second incident I have no doubts, because the disk made audible
noises. I'm just curious why it's always disk 4. Can the controller
conceivably do something that harms the disk? Just a statistical
anomaly?
It's a RAID 1+0 by the way, so there should be a nearly identical
workload on one of the other disks.
