Or try the hdparm command to change spindown time or other power saving
parameters. I use this to deliberately spin down my NAS drive after 10
minutes so it uses a lot less power and to get rid of the noise. I do
this at boot in /etc/rc.local

   # cat /etc/rc.local 
   #!/bin/sh
   
   # Set spindown time for disk
   if NAS1=`findmnt -n -o SOURCE /nas1/main`; then /sbin/hdparm -S120 $NAS1; fi
   
Rather than hard code the disk as /dev/sdc I use 'findmnt' to get the
disk name from the point it's mounted at (/nas1/main in this case).

I also do this in my daily backup scripts in case the drive setting
gets lost, as it seems to do some times.
