--- Comment #4 from dgilbert@eicat.ca ---
Just having a thought to this.  Maybe it's obvious... but in my case the drive
was pulled without any shutdown at the ZFS level.  The error blocks are
typically between a few an maybe at most 100.  I'm _thinking_ that this is just
the matter of one transaction that partially made it onto the disk.

Since I don't have "great" labelling and I don't usually get led to work, I
often have to pull a few drives to find the right one... and since I don't know
offhand which is which, I can't shut them down in ZFS.  The errors on a scrub
afterward are reasonably likely ... upward of 50%, but not certain.
