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

[Akshay Srinivasan]

I could here the disk head parking , about 8s after GRUB was loaded.This 
really seems to be a problem with the firmware of the Harddisks.
Also I'd like to mention , that there is a difference between disk head 
parking and spin down , from what I could hear - from my hard disk - the 
disk head might be parked even when the disk is not spinning down - or 
up.There is another Parameter , to measure the number of spin downs - 
Start_Stop_Count - this one has a minimum threshold of ~30000 before 
failure.
