30 What if I copied data to the drive until it was just about full. I'm
31 thinking like maybe 90 or 95% or so. If I do that and run the test
32 every few days, would it then catch a error after a few weeks or so of
33 testing? I realize no one knows with 100% certainty but I would like to
34 backup my data say every couple weeks just in case. If the drive works,
35 fine. If it fails, well, it wouldn't be the first time and it won't be
36 a primary drive so no big loss.

38 I got to find me a good drive for backups tho. I'm waiting on a good
39 sale of a brand other than Seagate tho. That should help keep two
40 drives from failing at the same time. Well, a little anyway. I think
41 it is called Dale's Law now. ;-)
