I have 2 Iron Wolf drives that are aggressively spinning down.
I have tried turning on the standby feature in "drive settings".
I have also run sudo hdparm -I /dev/sdc | grep level and get no output.
So I run sudo hdparm -S 120 /dev/sdc and get
/dev/sdc:
setting standby to 120 (10 minutes)
But nothing. I still see the drive in the "disks" utility with "zzz" immediately after copying a file over to the drive.
Can anyone help?
Thanks, Chris
EDIT: running 18.04

Your hdparm command doesn't work because you probably also have the udisks2 daemon running which spins down the disk on its own schedule (and/or overwrites your settings).
Thus, you can either stop/disable/mask that daemon, e.g. to just temporarily stop it:
systemctl stop udisks2.service
Or change the StandbyTimeout= udisk2 setting for your disk.
