Hi i have already tried to find the solution of this problem but so far most have been regarding 'emptying trash' which i have already done. Basically i filled my external seagate 500gb hardrive up with movies - then because a friend wanted me to give some music, i freed up some space on my hardrive by moving 110gb worth of films on to mac internal hd. Anyway, its now come to the point where i'm trying to put these films back on to my ext hd - however it won't let me put them on. when i right-click my ext harddirve on finder and press get info it says 'capacity 499.76 - available 100.56bg- used 399.206g' but when i try and move a movie file back onto the ext HD - (yes i have tried doing 1 file at a time) - it is saying that there is not enough free space. i've tried 'emptying trash' and 'secure empty trash' - not sure what to do! please help!
