I've got a drive burnin machine that I use to test all of my new drives.
I boot it using the Ultimate Boot CD and fire up Darik's Boot and Nuke,
which I configure to do four passes of random data overwrite, with
verification of all passes.  This can take several days to run on a
large drive.  This seems to catch all of the early drive failures,
usually within the first pass or two.  So far I haven't had any drives
that pass this test fail within their next couple of years of runtime.
