[SOLVED] Option Spin down HDD in Kodi not working on Rpi3

[Nachteule]

Nothing has been changed since months. So I suppose that there is a process accessing this disk permanently.

You could watch file /proc/diskstats if there are any r/w operations

For example:

Terminal

cat /proc/diskstats | grep sda
8 0 sda 215763 2413 51477370 1340940 7516 668 7457608 3913710 0 1017580 5252710
8 1 sda1 215573 2411 51473410 1288560 7232 668 7457608 3913160 0 982210 5232440

shows you the stats of disk sda
