September 22, 20232 yr Hi, all the disks stay spun up when Time Machine is running even though it's set to only use disk 3! Its been like this for quite a while now, I've tried wiping and starting a new backup and also tried changing the filesystem from xfs to zfs. Neither worked! It's MacOS High Sierra I'm backing up from. Anyone had the same? Or is a bug? One thing I noticed is that whenever Time Machine writes to drive 3 there are corosponding reads on all the other drives! (see screen recording) Cheers, Tim Screen recording 2023-09-09 17.29.42.webm tower-diagnostics-20230922-1748.zip
