Also, when the IV is stored you can more easily look for accidental IV re-use, and if you can find hash collisions, them you can even cause IV re-use (if you can write to the filesystem in question). For GCM IV re-use is rather fatal (for CCM it's bad, but IIRC not fatal), so I'd not use GCM with dedup either.
