January 13, 20215 yr I have a seagate 4TB HDD connected to my Thunderbolt port for backups. When I run hdparm -y /dev/disk/by-id/ata-ST4000NE001-2MA101_WJG01NY8 the drive goes to standby but then wakes after 1 minute or so. All my Dockers are stopped and I have no VMs running. I tried iotop to see what was waking the drive but it doesnt show anything. The drive will also not go to standby automatically no matter how many seconds I set (minimum 5 secs). How can I check what's waking my drive and preventing it from going to standby automatically? Running 6.9rc2.

When it polls the drives for SMART data it wakes up my Seagate. Any ideas how I can stop it doing this whilst monitoring the other drives?
