Early on I noticed that, according to smartctl, i= ts Load_Cycle_Count is increasing every 2 or 3 seconds. I even asked Samsun= g about this, but they either couldn't give any clue or didn't want to, b/c= the Serial Number is from Turkey, so not from the European market. Anyhoo... I just checked the values: Power on hours: 11500 Start/stop count: 2797 Power cycle count: 2197 But the load cycle count is at almost 12.3 million(!). That just can't b= e right. I stopped believing that number a good while ago. OTOH, I just became a bit nervous when looking at smartctl's output...
