I have a hard drive that a re-formatted from its stock setting, MAC-OS Extended (journaled), to MS-DOS (FAT) so I could use it with something that needed this format to be readable. Now since re-formatting it to MS-DOS (FAT) it works with most files but some files don't work. I then re-re-formatted it back to its original MAC-OS Extended (journaled) settings and all the files that wouldn't work now work. So the files are of course fine, but I can't get them to work when its formatted to MS-DOS (FAT). Is there any program or interface that will allow this to work better? I only have access to a Mac and am not going to install Windows or Parallels or anything like that. Help is much appreciated. Thanks!
