Disk power-on hours

I’ve had my EX4100 for a bit over a year now, and I had a disk failure a few days ago. After replacement, I thought to check the disk age of all the disks. The storage → disk status page has a link to the S.M.A.R.T. data, which includes the Power_On_Hours parameter, so far so good. I examined all of the disks and they are all showing less than 100 hours, which is ridiculous - most of the disks have been on for over a year, probably nearing the 10,000 hour mark. What’s up with that? Is there a way to get the real data?

Running the latest firmware 5.26.119
