Expedient hard disk temprature and load cycle stats

watch -d 'sudo smartctl -a /dev/sda | grep Load_Cycle_Count ; sudo smartctl -a /dev/sda | grep Temp'
This command is a great way to check to see if acpi is doing damage to your disks by agressivly parking the read arm and wearing down it's life. As you can see, mine has lost half its life. I'm sure this could be shortened though somehow. It will use smartctl to dump the stats and then grep out just the temperature and load cycles for the disk (a load cycle is when a the read arm comes out of park and wears on the drive).
Sample Output 
Every 2.0s: sudo smartctl -a /dev/sda | grep Load_Cycle_Count ; sudo smartctl -a /dev/sda | grep Temp             Mon Dec 14 19:09:56 2009

193 Load_Cycle_Count        0x0032   163   163   000    Old_age   Always       -       113991
194 Temperature_Celsius     0x0022   098   083   000    Old_age   Always       -       49
