No, the "zero dtime" is a thing that just essentially means that a
deleted inode was never actually written out to disk after being
deleted, and it's fairly normal.

But the above does sound very strange indeed. It's not necessarily the
disk, it could be memory or something else (the fact that it succeeds
the second time in fact implies that the image on the disk is fine, and
that the potential corruption happened somewhere else).
