Really?

The original drive in my ancient pentium 200 computer has been running fine for about 13 years now (it just had a birthday last week).  I was poking around at the SMART attributes, and discovered the following:


# smartctl -T permissive --all /dev/hda

Not only has it been running fine for 13 years, it really isn't even doing that badly.  The Seek_Error_Rate is a touch high, but it's still above threshold.  I'm also somewhat surprised that Power_Cycle_Count is 20. Really? I've only shut down the computer 20 times?
