Benedict commented on CASSANDRA-10159:
--------------------------------------
In this instance it's more that the disk _state_ is unexpected, not that
there's necessarily been corruption. I don't mind terribly though, it just
occurs to me this may be a little confusing for operators
> Incorrect last update time causes dtest to fail due to unexpected errors
