Laptop Hardrive Killer Bug is worse than I thought

This problem seems even worse than I thought. I’m looking at the Load_Cycle_Count of my new harddrive. I see 17 spin-down/spin-up cycles within 12 minutes.

The output of various :
$ date
$ sudo smartctl -a /dev/sda | grep Load_Cycle_Count

Sat Oct 27 11:17:28 CEST 2007
193 Load_Cycle_Count 0x0032 200 200 000 Old_age Always – 501

Sat Oct 27 11:24:46 CEST 2007
193 Load_Cycle_Count 0x0032 200 200 000 Old_age Always – 513

Sat Oct 27 11:28:59 CEST 2007
193 Load_Cycle_Count 0x0032 200 200 000 Old_age Always – 518

I turned of my laptop, booted it from ac before generating this output.
