It's actually about spin down.
I already proved ( https://bugs.launchpad.net/ubuntu/+source/acpi-support/+bug/59695/comments/78 ) that hdparm is invoked with -S 4 which translates (see hdparm manpage) in "Set the *spindown* timeout for the drive to 20 seconds".
This is the real problem and it's not caused by the drive firmware or the computer's BIOS. It's the operating system's scripts that call hdparm to set unrealistic spindown times.
