From gnome-disks, it is confirmed that the disk:
- Standby timeout is 10 minutes
- APM is 127 (spinning down permited)
smartd is enabled with default settings.
But the drive is never spinning down.
If I do a “Standby Now” in gnome-disks, the drive can go to standby without issues. And it will not spin up without accessing it (by l
s /mnt/device, or similar).
My first target to check is polling interval of smartd, but I cannot locate where it can be changed.
How can I find out what is accessing the device so that it will not goto standby ?
