also look at the B parameter of the disks with hdparm.

manpage:
  -B     Get/set Advanced Power Management feature, if the drive 
supports it. A low value means aggressive power management and a high 
value means better
               performance.   Possible settings range from values 1 
through 127 (which permit spin-down), and values 128 through 254 (which 
do not permit spin-
               down).  The highest degree of power management is 
attained with a setting of 1, and the highest I/O performance with a 
setting of 254.  A  value
               of 255 tells hdparm to disable Advanced Power Management 
altogether on the drive (not all drives support disabling it, but most do).

Due to  this bug I have moved my server to debian 6, and all over sudden 
I found the value of B needed to be set to 128 to get spin down to work 
correctly, although the manpages say above 127 does not allow spindown. 
If set to 127 my disks spindown but spinup instantly, and with B set to 
128 all is working fine in debian, so it might help in Ubuntu too?

Title:
  Settings in /etc/hdparm.conf are not applied during boot

Status in “hdparm” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: hdparm

  After upgrade to Lucid the hard drives never spindown. The hdparm
  spindown settings (and most likely others) in /etc/hdparm.conf are not
  being applied during boot.

  This seems to have happened after removing the init.d script.

  Release:        10.04
