[Bug 59695] Re: High frequency of load/unload cycles on some hard disks may shorten lifetime

[Alexey Borzenkov]

I personally think the solution should be simple. First some parameters
in laptop-mode need splitting into LM_AC_ and LM_BAT_ (like
LM_READAHEAD), next someone should invent sane defaults that actually
work for a default installation. Next installer should autodetect or ask
(during installation) if user wants to run on laptop-mode or not. And
really, the only sane default for ubuntu would be hdparm -B 128,
provided that laptop-mode is actually working as expected. Because as
previously noted, shock protection is important.
