** Description changed:

  since 2.6.32, I need to hdparm -W0 /dev/sda to get full performance
  (e.g. hdparm -t /dev/sda while miranda on wine write continously a bit)
  
  also, with "disabled" write cache, the hdd-led lights at ca. 25% of full strengts while running miranda if write cache is "on".
  Didn't had that on 2.6.31.

  	Model Number:       TOSHIBA MK3252GSX                       
  	Firmware Revision:  LV010A
