Good to know! I've regularly used dd on drives, but not on ones that
were in trouble (maybe once ...)
But now drives are at the point that you cannot guarantee an error-free
scan even on just one pass,
People keep saying that. I've never encountered it. I suspect it's just
not the problem that the hysterical ranting makes it out to be (either
that or the pile of cheap and nasty drives I have here are model citizens).
I've *never* seen a read error unless the drive was in trouble, and that
includes running dd reads in a loop over multiple days continuously.
If it were that bad I'd see drives failing SMART long tests routinely
also, and that does not happen either.
