I just got my son an external Lacie Hard drive (firewire) for his older apple laptop. He is running 10.3.9 with a 800mHZ power/PC G4 1gb ram When i try to copy one of his i movie files into the disk I get an error that it cannot copy because the name is too long or it has characters not understood. I can copy other files (e.g. word)When i use the disk to transfer some of the same files on my newer mac laptop, I do not get this error and it copies fine. I tried to make sure added the application suffix to the file name and it still gives the same result. Any suggestions?
