Title:
  Excessive heat versus excessive parkings

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  If laptop's AC adapter is plugged in, the temperature of the hard disk
  increases very fast, up to close to 60 Celsius degrees, which is
  maximum, according to Western Digital specifications. and that happens
  without any apparent reason, I mean while browsing the Internet,
  reading online an article or writting emails. The number of parkings
  is almost constant in an hour.

  If the AC adapter is unplugged and only the battery is providing
  power, the heat is much lower, but the number of parkings is
  dramatically increasing, almost 15 in a minute (at each 3 or 4 seconds
  I can hear a click).

  I tried ACPI=off but it didn't help, in that case the heat was fast
  increasing even while running on battery only.

  I have a laptop Fujitsu Siemens (Esprimo Mobile V6545) with 4 GB RAM
  (one added by vendor), and Ubuntu 9.04 Jaunty. And for checking the
  above parameters, I used the commands: sudo hddtemp /dev/sda and
  respectively sudo smartctl -a /dev/sda | grep Load_Cycle_Count .

  It is so frustating that I think I can't let that continue anymore and
  try another OS. Please help. Thanks.
