Converting to NTFS
In order to use native compression, encryption, disk quotas, shadow copies and security. FAT/FAT32 partitions will need to be converted to NTFS.
Converting to NTFS is a one-way conversion. You cannot convert NTFS back to FAT/FAT32 without reformatting the drive.
If dual-booting with Windows NT 4.0, ensure that it has been upgraded to Service Pack 4.
Remember!! Window 9x/3.x and MS-DOS cannot read NTFS partitions.
This is the command you need to remember: convert /fs:ntfs
