what is the different between ntfs and fat ???
The major difference between FAT and NTFS is security.
If you have FAT partition then Security and Quota tap will not available.
But in case of NTFS is a much more stable format of partition and is the newest. If a NTFS partition becomes corrupt, it can sometimes be recovered with special software. NTFS can also recognize more space on a Hard Drive and is a much more efficient and faster format to use
