This would be what we use badblocks for --- and it's free.  :-)

That said, I have never once actually encountered problems with silent
corruption.  Typically, I have problems of the motor failure variety.
And let me tell you, those are fun.

I tend to kill my drives with hefty workloads, as opposed to age.  I'm
relatively used to replacing them once every three to five years,
as-needed.  And I have certainly learned the value of backups, the hard
way.  And again.  And again.  And again.  :-)
