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

[Alexey Borzenkov]

Hi pelm,

I had an exactly the same issue with my Samsung drive, I suspect this
could be happening because of overheating or some other hardware problem
causing superclicks if heads are not parked for more than a minute or
so. I'm tired of repeating that disabling power management is *not* a
solution. Minimizing disk access is. And that's what laptop-mode is for.

Please see my comments:

As well as a recent bug report to fix laptop-mode not working on
startup:

I'm surprised that it works so well for me for so long (despite
constantly fighting ubuntu "fixes") and yet there are no comments from
developers or anyone else.
