Hey People I got a 4tb external drive and need it to work on both mac loin and window 7. Been using fat32 for the last years but it only a 4gb on files . I just need to copy the files to the hard drive. then i will work on them on the hard drive. As well i tried ex fat. but had data trouble with that. eg i split my hard drive into 3. and both of the 2 ex fat worked really good to start off. but then one day it just stop and dint let me create folders, delete files and was really slow. wish there was a way mac os Extended worked on window 7. people got any ideas?
