Comment 4 for bug 24029

Thanks for the hdparm and dmesg outputs. Both look good, so we need to dig deeper.

1. Confirm that hal is not running: "pidof hald" should not print out anything.
2. Check whether dbus is running: If /var/run/dbus/pid exists, and "ps -p $(<
/var/run/dbus/pid)" prints out a line which says "dbus-daemon", it is running,
otherwise not.
3. Try to start dbus and hal manually: "sudo /etc/init.d/dbus restart". Please
give me the output.
4. Check whether hal is running: If "pidof hald" prints out a number, it is running.

Based on the answers to these four questions, I have further debugging steps.
Thanks!
