What is causing my hd to spin down very frequently, despite setting hdparm -S?
The non-OS drive of my ubuntu server (Oneiric 11.10) has been going to standby approximately after 10 mins of idle even though I've configured /etc/hdparm.conf to put APM to 255 and spindown_time to 1hr
/dev/sdb {
apm = 255
spindown_time = 242 # 243 1.5 hour 242 for 1hr
}
The question is, what else could be causing it to go into standby mode?
> hdparm -B /dev/sdb
/dev/sdb:
APM_level = off
(shows that hdparm.conf is taking effect)
Other info:
uninstalled pm-utils
installed acpid (only for the purpose of handling the power off button event)
installed noflushd (out of habit, but probably not necessary as I don't care to spin down my OS drive at all)
installed smartmontools
