Well. I think that hdparm -B 128 is a too low value... This is the problem!

I've set it to 200 and now I don't have an infinite number of head
parking as before!

you have to edit the files named 90-hdparm.sh in the directories and
replace 128 with 200
/etc/acpi/ac.d/
/etc/acpi/start.d/
/etc/acpi/battery.d/
/etc/acpi/resume.d/
Then insert and remove the AC adapter and wait to see if the head
parks a lot again

(I really don't understand why there are 4 duplicate files... They
could be symlinks...)
