I hope this is fixed before I have to upgrade to 3.19+ kernels.
Currently I am running Mythbuntu 14.04 (3.13.0-58-generic), and so far
it seems fine with my ST8000AS0002, which I am just using for archival
storage.  I have manually moved my oldest recording files over onto
it, and set it up as a new storage group that is never used for
recording, so MythTV only ever does playback and deletion on it.
