Hi,
i have a WD WD40EZRX with strange beaviour off btrfs check vs. btrfs scrub
running btrfs check --check-data-csum returns no errors on the disk
running btrfs scrub on the disk finds tons of errors
i could clear the disk and send it to anyone intrested in ;-)
That's because --check-data-csum will only check the first copy of data
if the first copy is good.
I've submitted offline scrub patchset to address this, which is a
btrfs-progs equivalent of kernel scrub.

Thanks,
