Thanks for the reply Mitchell. After trying some more things I found out 
that the problems is that if I run scripts that are on /mnt/dados/ which 
is a mounted fat32 partition this problem occurs. On the root partition 
everything goes fine. But why doesn't it work on fat32 (or maybe with 
any mounted partitions)?

Thanks
