hard drive head parking in linux

[Jerry James Haumberger <jerryjh@imt.net>]

Hi, folks --

Does Linux automatically lift the heads of a hard drive off
of the disk after some time of non-activity?

Does it also park the heads as a part of the shutdown process?

I understand that early PC hard drives had to have their heads
parked when shut down, but that the later hard drives do this
automatically.  Under DOS with most of my older PCs, I've used
a few small utilities that perform both of the above functions.
One such utility lifts the heads after a period of inactivity
(a TSR) after a predetermined number of minutes.

This is important to me, since I find it useful to preserve the
old hard drives of PCs in my collection, which will also include
some Linux machines...

Thank you for any knowledge on this matter!
