I'm now wondering whether this is "normal"? I guess so, as the hard drive gets disabled during the suspend, and after a wake-up it gets re-enabled, so any changed made with hdparm don't get stored. Is this intention right?
Your BIOS probably resets it to 127.
Secondly I want to know what would be the right file (place) to fix this. I'll have to execute the hdparm command again, but don't quite know where to put it, or at least where it should be put ;).
I just replied to another e-mail from you, regarding pm-utils... and I said that it exposes a nice way for writing your own hooks. For example you create an executable hook (script) /etc/pm/sleep.d/03disk-power-management with contents: #!/bin/sh # # Set HDD advanced power management to it's lowest value. case "$1" in thaw|resume) /sbin/hdparm -B 254 /dev/sda >/dev/null ;; *) ;; esac Notice I prefixed the name with 03. You can see other pm-utils hooks in /usr/lib/pm-utils. When machine is suspending they are executed by the order of their names, on resume they are executed in reverse. Above hook does nothing on suspend or hibernate, but when waking up it is executed, at the end. Usual practice is that hardware hooks have low or high numbers (depending on what they do) and those dealing with software are in between. -- Adrian C.
