Hello. My new Iron Wolf 10TB drives are aggressively spinning down in Ubuntu. Does anyone know how to prevent this? I have tried setting the standby time in drive settings. I have also tried setting the spindown through hdparm, but nothing works. The moment a file has finished being written, they go back to standby.
Has anyone got any ideas? Seagate told me they cant help me because I'm using Linux...
Cheers,
Chris
typical seagate Desktop aggressive power saving.
a simple way is disable APM by running hdparam
to check APM level: hdparam -B /dev/sdX
to set APMlevel: hdparm -B <1-255> /dev/sdX
unit to install hdparm package that based on your running linux distro
could be off (does not mean disabled ), 1 to 255. but the number does not reflect identical how aggressive power-saving on seagate or WD. this number is useless and can be try by trial
seagate (based on my SG HDD, barracuda and current SMR drive including 5TB 2.5 SMR): 240 or greater turn APM is disable.
WD white label ( has 8T and 10T), default is off but it would parking/spinning down within 5 mins. 200 or greater turns APM to disable
seagate is very aggressive compared WD. I do not know on NAS drive due on not having it.
I have a simple script that installed as a systemd unit to disable APM for all HDDs.
if you need the script and systemd unit file, I can post it here.
