[ale] Did WD15EARX consume my weekend?

[Jim Kinney]

That really sounds like a majorly bad drive. Pop it into an external case,
format it as a single partition and copy a bunch of large files over to it
(.iso's are good) then run a diff. I'd bet the diff fails. I suspect the
drive has been dropped and the head is misalligned. Return it ASAP.

As long as the general population is passive, apathetic, diverted to
consumerism or hatred of the vulnerable, then the powerful can do as they
please, and those who survive will be left to contemplate the outcome.
