 Hmm that is strange. On my laptop, the internal hard disk always spins
 and I never experienced it to stop doing so (plain booting from USB stick).

We've started discussing this on the Please review  merge
bugfix/less-aggressive-hard-disk-APM-on-AC thread, back in March 2013
(and possibly the thread starts earlier). The discussion was a bit
painful, so I never got around to finish the draft email that's been
waiting half-completed in local storage.

I'll take this heads up as an opportunity to get back to it, hopefully
in the next few days. Thanks!

Cheers,

 (up to complete silence when the fan is not spinning), and proof to the
 user that Tails is not accessing the HDD.  Of course, the HDD need to
 spin-up again if the user mounts it.
 
 but what I cannot comment on is whether there may also be difficulties
 from spinning-down the HDD (hardware failure? ...)

[Tails-dev] idea: stop HDD by default?

2015-01-06 Thread flapflap
Hi all,

I was thinking whether it makes sense to by default spin-down the
harddisks, e.g. via hdparm -y /dev/sdX or hdparm -Y /dev/sdX

That would have the advantage of reduced power consumption, less noise
(up to complete silence when the fan is not spinning), and proof to the
user that Tails is not accessing the HDD.  Of course, the HDD need to
spin-up again if the user mounts it.

but what I cannot comment on is whether there may also be difficulties
