I have bought a new laptop ASUS N56VV last week. I installed a new SSD(/dev/sda) and moved its original HDD to optical drive as secondary harddisk(/dev/sdb).
I just migrated archlinux from my old laptop and everything is well except this one:
When I shutdown my laptop it shutdowns in less than 3 seconds(fine), but I can hear a terrible noise from the secondary HDD. It sounds like I cut off its power directly. Same issue does not exist under WIN7.
What should I do to fix it?
Thanks for any help!
Desktop Environment: LXDE
Tweaks: hdparm -B 254 /dev/sdb
I also add "acpi_osi=" to kernel options for my Fn keys.
