I don't understand this. Continuous system freezes while making "HDD head moving and spin up sound". I have laptop-mode-tools off. APM disabled with mswindows tool.
If you need any command or log to help me, I'll paste on pastebin.
$ sudo hdparm -B /dev/sda
APM_level = off
$ sudo smartctl -A /dev/sda |grep Load_Cycle
193 Load_Cycle_Count 0x0032 094 094 000 Old_age Always - 75929
// and growing..
