When I had a sd-card error I installed meteohub again and put my weather data back to /data/weather/YYYYMM/*
Now I had the problem meteohub freezes every time while it's recompute the data, so when it freezes I cycled the power and freezes again after 3.5 hours and so on.
I removed the weather data and meteohub does not freeze anymore

But I realy like to but back the usefull data I gaterred in these six years of data.
Is there a way I can repair these raw data files?
