[PROBLEM] HDD wakes up himself after some time

[mk01]

@Alcoinus,

can you post what hdparm is actually doing on the drive ?

Code:

sudo -i
DEVNAME=/dev/sda FORCE_RUN=yes VERBOSE=yes /etc/init.d/hdparm hotplug

the above command will output on screen hdparms action and will run regardles of "nohdparm" setting in /boot/cmdline.txt .
(just btw a better solution to let hdparm work on your xbian is putting "FORCE_RUN=yes" line into /etc/default/hdparm as some parameters in cmdline.txt can change with updates)
