I checked my old(purchased in 2009) SAMSUNG HDD with two tools. One is CrystalDiskInfo(CDI) and the other one is HD Tune(HT).
At first, with CDI, no problem was detected and it just said 'Good'. However, with HT, it shows some problems:

Health Status : warning
As you can see, HT reports 01, C4, and C7 as non-ok status. Of course, the other columns such as Current, Worst, Threshold and Data are coincident with those of CDI although CDI does not report any error.
Which result should I trust? Does this HDD have problems and should I abandon it? Or Can I just ignore reports in HT? FYI, the benchmark in HD Tune under just-formatted state shows extremely clean steps(see http://postimg.org/image/l1d2t23k5/).
Worst < Threshold
then you might have a problem.Current
and notWorst
?), but my general instinct would be not to trust the drive for anything that is not using a proper checksummed filesystem and with data for which I have a solid backup.
