Is your Load_Cycle_Count continuously increasing? You mention a laptop and at one time there was a big problem with disk drives continuously parking the drive head. It has been a few years since I have heard of this problem. # apt-get install smartmontools # smartctl -a /dev/sda | grep Load_Cycle_Count # smartctl -a /dev/sda | grep Hours Look for parameter 193 Load_Cycle_Count and see if the raw value of it is continuously increasing. > # hdparm -I /dev/sda | grep level > Advanced power management level: disabled I think that should disable agressive power save management but I still think it is necessary to look directly at the load cycle count to know for certain. > smart, hal : not installed Install smartmontools. I also think think you should set up regular drive selftests. Ask if you want me to suggest something about this. Bob
