Hey guys. I have a quick question .... I dont know if this just happends to me or not so i would like an input. When I try to copy files bigger that 5GB Mac Osx doesnt let me copy to my external HD and give me an error like -1309 bla bla (I cant remember what it says) I have a MBP C2D 2.33, 2GB Ram running version 10.4.8 two external HD both Western Digitals 1. Mybook Pro 500GB Firewire 800 2. WD Passport 120GB USB 2.0 (I just got it today) So Im wondering if someone else is having the same problem ? Do you think it could be the HD I tried in windows and there's no problem with any kind of size Both HD are format in Fat32 so can be compaible with Windows and Mac. Thanks guys.
