The manufacturer has built spare disk sectors into the drive. As sectors 
fail,
they're automatically detected by the drive and replaced by spare sectors.
Once the pool of spare sectors is exhausted, the drive is no longer able to
do this and bad sectors become visible to the outside world.

With a new drive, presumably  the pool is far from being exhausted.
