I just think that's a bogus argument. Even if we accept that the refurbished drive is more likely to fail than a new drive, any data that's "too important for a refurbished drive" is too important to not be backed up.

My feeling is that any drive that's working properly now is no more likely to die than any other. I could be wrong, but then, these go into a raid array where it's not really an issue.
