Hi, last night we noticed that our Manhattan TR3 has lost all recordings on the hard drive before 8th March 2021. It currently said it has 88% of spae, it has a TB of memory and we've had it around a year so I can't imagine we filled it up yet. And in any case, I would imagine it would issue some kind of warning that the hard drive was full before wiping them? Anyone have any idea what might have caused this and if there's any chance of recovering what we've lost? Thanks!
