Thank you.

 Reallocated Sectors Count treshold is 5 and the dec value is 24. That is what is causing warning for the disk. Should I return it (hd is almost new 900 hours of operation) ?

Current value is 100, threshold is 5, you'd get a SMART failing now if it ever reaches that., the warning on unRAID is not because of the threshold, it's because there are reallocated sectors, it's never a good sign, but it they remain stable it may not be an issue.
