Hmmm. All this talk about bad cables by you and others sounds more like older

drives. Was your experience with a recent drive and controller?

I certainly haven't found them to be common, unless a drive was on the verge of
major failure. Though if a drive is used beyond its service life (usually 3 -
5 years) they may become more common.
In any case, if a conventional scrub would detect the bad sector then ZFS per
se wouldn't add unique value (save that the check would be automated rather
than something that the user, or system assembler, had to set up to be
I really meant it, though, when I said that I don't completely discount
anecdotal experience: I just like to get more particulars before deciding how
