Converting FAT to NTFS
FAT can be converted to NTFS, but there is no way to convert an NTFS drive back to FAT.
The utility is a command line program: CONVERT.EXE.
Syntax: convert drive: /fs:ntfs
If a process, including Windows NT itself, is currently accessing the drive, an error message appears. The error message provides an option to schedule the drive for conversion when the system reboots.
If the conversion has been started upon reboot the user wants to stop the process, rename Convert.exe. The conversion cannot continue on boot without this file and will be cancelled.
CHKDSK has been upgraded in Windows NT to work with both FAT and NTFS file systems. This is still an important utility to run, especially if FAT is being used. However, NTFS can detect corruption during the boot sequence and initiate CHKDSK during the blue bootup screen.
Note: There is no Defrag utility included with Windows NT.
