I changed my hard drives 2 weeks ago, and two of the four 1TB drives are SAMSUNG HD103UJ, and both report very high number (and growing) on SMART attribute 195, Hardware ECC Recovered. Currently one is 40214632 for 222 hours up, and the other 23702532 for 217 hours.
More searches on Google gave me people with exact same disk and same question, and few people with other Samsung, but never any explanation
I looked at my other hard drives (non Samsung), and they actually don't report this attribute, so I started thinking that maybe the number of errors fixed by the hardware is always high but usually hidden.
Then, I found some emails of people who have 15 or 50 errors, so no, it is not normal to have dozens errors fixed each second.
Does anyone have an idea of what this value means on Samsung hard drives?
