If there is a pending sector -before- the wipe, the drive has failed our testing process. If there is a pending sector -after- the wipe, the drive has also failed our testing process.
See, a pending sector can only be detected by a read. Without a full read, how many hidden failures have you "covered"?
When I refurbish drives for myself, I always do a full latency and read test, and then a full wipe. Only with this order of procedures would you know the real condition of the drives. You claim that you care a lot about drive healthy, but you are not even doing it correctly. Doing a full wipe before a full read, is like throwing a bottle of anti-biotics on a patient without even trying to do a blood test. You not only misunderstood the process of treating, but also misunderstood the process of diagnosing. Relying on observing a pending sector before a wipe, is like buying a lottery. The former customer must be so lucky to read the broken sector to trigger a pending sector. If a broken sector is never read, a pending error is never raised.
Let me rephrase it. Someone may or may not be sick. If someone has a fever (a pending sector), you diagnose it (do a latency test) and try to treat it with anti-biotics (do a wipe), and check their temperature again. Even someone doesn't have a fever (no pending sectors) they could be in suboptimal health, and you can still diagnose it. Now you were claiming that giving anti-biotics can cover a hidden cancer, so we shouldn't treat it, we should simply claim the patient is gonna die soon.
And in the quote, you are basically blindly throwing anti-biotics to anyone who's visiting, and claim that they are healthy without knowing how to correctly check them.
Don't get me wrong, in businesses it's common to do things like this, because this seems to be most economical. You can just hire some guy for cheap, to look at the numbers. 0, good, 3, bad, job done, easy peasy. You can't expect them to have 5 years of hard drive diagnosing experience on the resume, right?
There are of course other business strategies, like all servers are decommissioned after support period, all hard drives are drilled to pieces to prevent data leaking, etc etc.
But again, those business strategy don't apply to home users, or individual cases. I have no problem with you doing so in your data centers, but if you walk into a doctor and ask why he's bothered to do a blood test or a CT scan or give anti-biotics instead of just burying the patient in the backyard, it would be a silly move.
