[QUOTE="chscag, post: 1209649, member: 46727"] Are you sure that drive wasn't formatted as "exFAT" rather than FAT-32? I can't imagine formatting a drive that large to FAT-32. There would be a tremendous amount of cluster waste and slack on a drive that large. Typically, manufacturers format large drives to NTFS to avoid cluster waste, but lately some are using the "exFAT" system. See this [URL="http://msdn.microsoft.com/en-us/library/aa914353.aspx"]LINK[/URL]. And a note: Disk Utility would "see" an exFAT partition or drive as MS-DOS but would refuse to access it because it doesn't know how. [/QUOTE]
