I installed laptop mode tools, I have watched as the hard drive is accelerated when I’m doing nothing for a few seconds and then do any move. Does anyone know if this in the long be detrimental to the hard drive?
Apparently low revolutions every few second and then when you do something accelerates or becomes active again, it is observed by the noise and do not know if these constant changes will affect the life of the disc or no problem.
In another distribution when used tlp not feel this, here this tool is not available.

I’m not aware that there are hard disks that can run at different
rotation speeds (although it looks reasonable). The fan, yes. Maybe you
hear the fan changing speed?
On the other hand, openSUSE has a number of tasks that run periodically
and may start up the hard disk. Laptop mode tools should delay or
disable most of them (known ones). It is adjustable.

hard disk has no fan but the CPU does have one and it varies in speed according to the load. Also a DVD will speed up and slow down with a nice whining sound if you read from it. Hard drive can spin down to conserve battery life but that generally is either full bore or off and it generally only spins down after a very large time ie minutes. A CPU though can have the load change a great deal and it will generate more heat the more it works and require more cooling witch cause the cooling fan to run faster. This can happen frequently depending on the load. Modern HDs are very quite and difficult to hear but the cooling fans are pretty loud. and DVD drive can be load also
Yes, I agree that what you are almost certainly hearing is the laptop fan, changes speeds regularly to match the heat output of the cpu. It is unlikely with modern laptop HDs that you can even hear the drive when it spins. But, the laptop fan kicking up speed is relatively a roar.
I can distinguish between fan noise and hard disk. laptop mode tools within seconds slows the hard drive and when I do a move the hard drive again increased his speed and sounds slightly when accelerating, it’s similar to when you turn on an external disk.
My question is whether these changes in speed can affect the life of the drive.

Please tell us the exact model of your hard disk (not of the computer).
I have never seen a hard disk with variable speed. Assuming your disk is
sda, please run in a terminal (konsole, xterm, whatever):
su -
hdparm -I /dev/sda
smartctl -a /dev/sda
and paste it all here, from initial command prompt, to last command
prompt, in a single mouse sweep, and please do so inside code tags (the
‘#’ button in the forum editor). http://susepaste.org/images/15093674.jpg
Then we can perhaps find the hard disk specifications and learn if it
can do variable speed or not.

It seems that it simply spins down completely and soon after it spins
up, completely. Which is typical, but probably wrong if it happens so
fast. A laptop unit should be able to cope with this, but you can adjust
the settings of the tools so that it delays action more.

Sorry, I don’t understand.

Ah. About that you have to ask in the feedback forums
support-information area. As I don’t use the web interface, but nntp, I
have no idea.
However, I pasted your link above and it works fine. But I’m not logged in.
