Thsi seems to be an issue with your drive not implementing APM according
to the standard.  Nothing that can be done in the hdparm package to fix
this.

Title:
  harddrive spins down when man page says setting does not permit it

Status in “hdparm” package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: laptop-mode-tools

  I'm beta testing Ubuntu 8.10 Intrepid Ibex with kernel version
  2.6.27-7.

  In laptop-mode.conf, the hdparm -B value is set to 128 therefore
  [according to man page] the harddrive should apply power regulation
  without spinning down the harddrive

  hdparm -I /etc/sda1 indicates that hdparm -B is indeed set to 128 (and
  not 0 through 127, which would elicit spindown). It will still spin
  down because of -S. The man page should be clearer about this.
