Hard to say. I would backup all data that you have on this disk.

There are 3 pending sectors that you need to rewrite to be able to 
re-run smartd long test. A suspicious thing is that three long tests 
stopped on different LBA_of_first_error - it may be an not mechanical 
problem, but hdd electronics.

My advice is - after doing a backup to run badblocks read-write test[1]. 
If it passes then you should have 0 "Current pending sector" reported by 
smartd and "Reallocated_Sector_Ct" set to 3.
Then you can run smartctl --test=long and see if it passes.

Anyway, this disk is suspicious and I would not use it without constant 
backup.
