You expect some number of sectors to "go bad" over time.
But, the drive should reprovision a new sector to replace
the "failed" sector ("Grown Defect List") -- preferably before
it can't reliably recover the *data* from that sector!

It's only when this starts to happen at an increased
frequency or at a large cumulative rate that you have to
worry about the drive being toast.  (or, on its *way* to
being toast!)

Presumably (?), for a DVR, there's nothing particularly
"precious" about the data in that sector (if there had been,
the question becomes:  "Why didn't you have it backed up?")

Do you see a performance problem, otherwise?
