Disk FAT type to NTFS

For a Fixed Disk, Microsoft Windows XP supports the following three file systems:
FAT16
FAT32
NTFS
Because NTFS has high performance and high security and reliability, we recommend that you use NTFS in Windows XP. This article describes how to convert a FAT16 or FAT32 volume to NTFS.
Requirements
Note the following restrictions and requirements before converting a FAT or FAT32 volume to NTFS:
Udfs and CDFS are only used for optical media and cannot be converted to NTFS.
A floppy disk can only be in FAT12 format.
Some early programs were not written for Microsoft Windows NT 4.0 or Microsoft Windows 2000. After the FAT32 file system is converted to NTFS, they may experience performance degradation. This issue does not occur in clean NTFS partitions.
You can use the conversion command (convert.exe) to convert an existing FAT or FAT32 volume to NTFS. .
The conversion to NTFS is a one-way conversion process. Once the drive or partition is converted to NTFS, it cannot be restored to FAT or FAT32. To restore a volume to the original file system, you can only reformat it to FAT or FAT32. This operation will delete all existing data, including your programs and personal files. In this case, you can only recover data from the backup or reinstall the operating system and program.
Convert.exe requires a certain amount of available space on the drive or partition for conversion. If convert.exe determines that the volume does not have sufficient available space, the volume will not be converted.
If your computer is running Windows XP and other Microsoft Windows operating systems, note the following:
Only Windows 2000 and Windows XP have full access to files on NTFS volumes.
Windows NT 4.0 Service Pack 4 (SP4) or later can access files on NTFS volumes. However, if files are stored using certain functions in the latest NTFS version, some restrictions will apply.
Microsoft Windows Millennium Edition (Me), Microsoft Windows 98 Second Edition, and earlier versions and MS-DOS do not have access to files on NTFS volumes.
How to convert a FAT or FAT32 volume to NTFS
Note: Although there is little possibility of corruption or data loss during the conversion process, we recommend that you back up the data on the volume to be converted before starting the conversion. To convert an existing FAT or FAT32 volume to NTFS, follow these steps:
1. Click Start, point to all programs and attachments, and click command prompt ".
2. At the command prompt, type the following content, where drive letter is the drive you want to convert:
Convert drive letter:/fs: ntfs
For example, enter the following command to convert drive E to NTFS:
Convert e:/fs: ntfs
Note: If the operating system is on the drive to be converted, you will be prompted to set a schedule for the task when you restart the computer, this is because the conversion is not allowed during the operating system operation. When this prompt appears, click "yes ".
3. When the following message is displayed in the Command Prompt window, type the volume label of the drive to be converted, and then press Enter:
The file system type is FAT.
Enter the current volume label of drive letter
