True .. but all you really need to know is that as far as your disk 
vendor is concerned, your error rate is 87 (somethings), the worst it's 
ever been is 83 and if it were nearer 6 somethings, you should worry :)

 9 Power_On_Hours          0x0032   089   089   000    Old_age Always -       10155

Seagate says you're only 11% on the way to (mean) oblivion .. if you 
believe it should run 11.4 years.  We had one 4GB IBM drive that did!
