A few weeks ago I switched on my device and was informed that I would have to format it. I did this although I would lose approx 350/400 GB of data. All was well for a few days but then the same thing happened. Device worked perfectly until about two in the morning then when I switched back on about nine the same message but this time the device did not format. Device is approx 3.1/2 yrs old and on FHTCP 1.03.12.
