I have a 2TB western digital hard drive that I will have formatted to MS-DOS or fat 32 with disk utility, but later on would like a partition to accommodate files bigger than fat 32's file size limit. can I do this? & how? also, if I have cloned the contents from another hard drive onto this 2TB one that is just formatted as one whole fat 32 volume, can I make a partition with another format for bigger files? or must the drive have no content on it? what I mean is if there is room on the 2TB drive, can I make a partition with disk utility to the free space & leave alone the part that is fat 32 with content on it? or must the whole drive be blank? say later on, I want to move my bigger files to another separate drive, can I wipe the partiton off the 2TB drive? & still have the fat 32 partition with it's content?
