Good afternoon, This weekend I tried to copy files to my external hard drive. It was formatted as Fat32 so I can hook it up to a media box, tv, ps3, etc to watch my movies. I know that the format is limited to 4 GB, so in order to watch files that over over that, I have reformatted the drive to Exfat and as a test, tried it out on a 32 GB flash drive copying over a 5GB file with success. I then reformatted my 3TB external drive to Exfat and copied all of my orginal files over to it without issue (files range in size from 1GB up to 4GB. I then tried to copy over some new files, ranging from 2GB up to 7GB. None of the new files wold copy over. I got these files from my friend from a NTFS hard drive. I was able to copy them to my mac book pro from his hard drive without issue but they will not transfer to my newly formatted exfat hard drive, although one file (5GB) did copy over to my newly formatted 32GB flash drive. Thoughts?? Thank you in advance.
