How to convert FAT file system to NTFS

How to convert FAT file system to NTFS

The advantages to using the NTFS file system:

·        Ability to encrypt files on the hard disk (Windows XP Pro only)

·        Set security permissions on folders and files allowing only certain users to access, write or delete.

·        The ability to set quotas

·        File compression

·        Supports larger partitions (32Gb limit for FAT32 when installing Windows XP, with NTFS volumes of 2 TB and greater are possible) and file sizes than Fat/32 (On an NTFS drive the maximum file size is equal to that of the drive volume, on Fat16 there is a 2Gb size limit on each file, with Fat32 this is 4Gb).

·        Improved resilience to data loss and efficiency vs. FAT

NTFS conversion should not be done in the following instances:

·        In a dual boot scenario with another operating system that cannot read NTFS (Such as Windows 95, 98 or ME) when converted is the boot drive. (Converting the boot drive will prohibit access to operating systems that cannot read NTFS).

·        If you wish to access the converted drive using a dos boot disk (A 3rd party utility must be used to access an NTFS drive via Dos, encrypted files will remain inaccessible to dos).

·        If you have upgraded from Windows 98 or ME and wish to uninstall Windows XP without having to reformat your hard disk.

With FAT formatted drives created with earlier versions of Windows there may be 2KB system sectors before the data starts and as the cluster size is often larger than 4Kb, you may end up with 512byte clusters which aren’t incredibly efficient conversion. You can align the data into a 4Kb area before you convert with a tool such as BootitNG - Compare Cluster Sizes FAT32 partitions formatted by Windows XP do not contain 2kb system sectors..

To convert a drive, Go to start >> select run and enter cmd into the run box. When the cmd window appears enter the following as shown in the picture below:

convert drive_letter: /fs:ntfs

Within Windows, convert will not be able to obtain exclusive access to your hard drive if any files are in use, as such the conversion must be done the next time Windows starts to load 

On the next reboot the process will start by checking the drive for errors, before proceeding to determine the disk space required for the conversion and thereafter the conversion of the file system to NTFS.

Your drive should now be using the NTFS file system.
