    So I tried hooking up my WD External Drive to me new Mac Book Pro tonight, but for some reason it won't let me copy files to it. I wanted to back up some images I took last weekend, but I am not having any luck. For some reason I don't have access to write to the drive?

    What is the drive formatted as? It sounds like NTFS.

    If you click on the drive and press cmd + i, what do you see here?

    Try changing it.

    You can only read...

    It is formatted as NTFS. Can I fix that and reformat it?

    Yes, you can reformat it in Disk Utility.

    So does a Mac have a limit with file size if not using NTFS?

    If the drive is going to be used only with a Mac - format it as HFS+, and there is no limit (that I know of).

    If you are going to be sharing the drive with Windows machines - format it as MS-DOS (FAT32), but there is a file size limit of 4GB.

    So HFS+ is just a mac file system? Thanks!

    Still learning the ropes!

    The only choice I see is MS-DOS(Fat). I don't see a choice for FAT 32.

    Oops. That is FAT32.
