NAS540 FW:V5.21(AATB.13) - HDD Sleep function not working

artwich

Installed Tweaks. Chose to disable MyZyxelcloud installer. Uninstall MyZyxelCloud. One hard disk went to sleep — very strange. Usually both disks go to sleep at the same time.

Rebooted. Decided to disable two more unneeded daemons -- something about Twonky and timesync.

Now both disks sleep as expected.

Meanwhile the misconfiguration should be solved, so you should see more packages now.

I just installed RandomTools. After that my hard disks do not enter sleep mode again.

Does RandomTools make changes my system? I thought It would only provide additional commands that I can use.

What's the difference between disable/enable RandomTools in App Center? (Neither setting will help hard disks to go back to sleep mode. Also rebooted, no help.)

Wondering if I should uninstall RandomTools?

Indeed RandomTools is not supposed to do anything. It mainly puts a number of symlinks and proxy scripts in the /bin/and /sbin directory (both ramdisk), which point to the binaries in the package directory.

With 'disable' this symlinks/scripts are removed again.

Tweaks has a 'Disk Monitor' which can log disk activities, in many cases including process names. You could use that, while leaving the NAS alone, so the disks should sleep, to see what is keeping them awake.

Many thanks for your reply. I will try the Disk Monitor.

By the way, after several hours of idling the disks now enter sleep mode. It used to be 10 minutes or 20 minutes depending on my setting.
