    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!

    OS X tends to be rather rude when writing to DOS formatted disks. For instance, it leaves a lot of bogus files lying around like .ds_store, and ._ files like ._somesong.mp3 which tends to confuse mp3 players because the . files are nothing but preference files that are not needed in other OS.

    It's no different than Windows creating thumbs.db and folder.jpg files that mean nothing to Mac OS X.

    For an macbook air with 256 GB drive and about 20 GB used how much space should i calculate for time machine to backup.

    When i make an Hfs+ and a fat32 partition with disk utilities does hfs+ need to be the first one in order that time machine runs?

    God damn it. The files that won't transfer over are each bigger then 4GB. So what the hell can you do to get around this? I am trying to copy media files (movies, music etc) onto this hard drive to use on the new Oppo BDP-93. In the manual it says it only supports/reads FAT32 HDD's so what are my options?

    According to page 42 of the OPPO BDP-93 Blu-ray Disc Player User Manual (PDF Format):
    Install NTFS-3G on your Mac (link in my earlier post), format the drive to NTFS, and you're set.

    "I only have access to a Mac and am not going to install Windows or Parallels or anything like that."

    If you are "only have access to a Mac", then there is only ONE file system that you should be considering, and that is a Mac OS-based filing system.

    Anything else is playing with fire.

    Why would you even consider using anything else?
