ho da poco comprato un HDD esterno portatile USB3 della Maxtor : M3 4TB.
Ho però un comportamento anomalo : quando trasferisco file grandi da 30-50 Gb il transfer è ballerino, si passa da 100 a 20 poi a 50, 70, 20 etc...
Non ne capisco il perchè e non ne vengo fuori...
Posso chiedervi lumi a riguardo e se sto facendo tutto correttamente?
