How to format my drive for Windows only (NTFS)?

If you expect to have files greater than 4GB you will need to change your drive format to NTFS. Microsoft provides a utility called “Convert” which allows you to change the format to NTFS with your files in place. You can find instructions for Convert at this link: http://technet.microsoft.com/en-us/library/bb456984.aspx

If you would rather re-format your external drive, proceed as described below.
