Hello. I have a usb hard drive connected to a raspberry pi 3 running LE 7.90.006. This hard drive parks its head after 2 seconds of inactivity. I can prevent that by connecting through ssh and typing 'hdparm -B 255 /dev/sda'. But after 20 or so minutes it spins down, and when i open something it spins up and starts parking its head again. Is there a permanent solution to this? I googled for a bit and found that adding 'apm = 255' to /etc/hdparm.conf should work, but there is no such file and i can't create it because the file system is read-only.
Disable hard drive's APM

Place the hdparm command in the autostart.sh file. Any changes in /etc/something will be wiped with the next LibreELEC update.
Depending on what is happening in the fore-/background, of course the hdd might spin up.On the other hand, just after 2 seconds of inactivity is pretty quick.

I already did, but that just runs the command on boot. So i have to enter it manually (or reboot the rpi) after the drive spins down.

use
also, can you check the output of the following command after the disk goes to sleep to see if the value has changed?
you can also try using
as this should disable the disk from sleeping at all.

I tried setting apm to 254 and after 20 minutes it parked its head and spinned down almost immediately. Then i checked with 'hdparm -b' and it said 128.
I guess i could solve this problem by disabling sleep, but i'd rather not do that...
