Hi everyone,
I installed TOS 6 on SSD only (removed all HDDs during setup), then reinserted the HDDs and created a storage pool. At first everything was quiet, but after a few reboots, one HDD now has constant activity even when idle.
Is TOS 6 copying system partitions to the HDDs automatically? How can I force it to keep system data strictly on the SSD? Any advice would be appreciated!

TOS6 won't copy system partitions to non-system disks automatically.
You can use the `hdparam -Y` command to put the hard drive into hibernation mode.
Additionally, you can use the following command to check who is waking the HDDs: `blktrace -d /dev/sdX -o - | blkparse -i -`
