K45 · Disable hard drive's APM K45 October 1, 2016 at 8:00 PM

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...

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.

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.
