Neither do I, but I've noticed that the measurement units across different HD vendors (I've only worked with IDE/SATA) are not standardized, so you need extra software like smartmontools or HD Tune to convert them down accordingly. However, OpenBSD's atactl(8) is capable to read the values, check them for errors and print the raw data in hexadecimal format. > Now is that something that is suppose to be done only at the start by > the bios for example when the computer is turn on, or all along the way > at regular interval and provide valid data or is it all crap and > marketing only hipe? AFAIK BIOS only toggles SMART enable/disable and I'm not convinced it has any actual effect more than "atactl wd0 smartenable / smartdisable". The data are used for sales returns on regular basis. > I wonder if that's not such a stupid idea if having it in sysctl may > make any sense or not.

That's not for me to decide, but because of the differences in data provided by different drives I prefer the old way. > There is paper on this, but in real life is that's actually any good? > Would this be useful? Is smart actually trusted to be of any value? Yes. -- Martin Pelikan
