Oh, given my previously elabored backup configuations I have one further thing I would like to do. Since backup 1, and 2 are only used once per day I would like to spin down the hard drivers to increase longevity. I figured dismounting the drive would be effective, but I have encountered several things. First, usb drives are auto mounted, therefore there is no entry in fstab, and no folder in /media. If you dismount backup1:

sudo umount /media/backup1

Now just before issuing the backup rsync I would like to mount the hdd and spinup the hard drives:

sudo mount /dev/sdg1 /media/backup1

But the platters still feel like they are spinning. There is a hum to the disk, and it remains warm as if the partition was still mounted. Maybe I’m confused as to what a spindown is? I would like the hdd to be pseudo disconnected, even the the cable is connected, and then pseudo connected when data transmission is required just before the backup routine.
