Usually, the reallocated sector count is the one to watch and that seems
to be fine with your disk.
SMART in general tends to be a very bad predictor of drive failures -
most disks fail without showing up (i.e., one drive head will go bad) -
or it causes false positives which end in you pulling a reasonable drive.
Absolutely. If you disk supports it, you should run a long diagnostic test
