I bought my current internal laptop disk for Christmas 2008. It's a Samsung HM500JI (with 500 GB). Early on I noticed that, according to smartctl, its Load_Cycle_Count is increasing every 2 or 3 seconds. I even asked Samsung 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 be right. I stopped believing that number a good while ago. OTOH, I just became a bit nervous when looking at smartctl's output... Reallocated sectors: 7 (threshold 10) Calibration retry count: 1631 Load retry count: 1631 -- Gruß | Greetings | Qapla' Please do not share anything from, with or about me with any Facebook service.
