Convert windows drive or disk file system from FAT32 to NTFS without losing data

Hi all,

I had a problem with my external hard disk when copying some 25GB file.

I had troubleshoot the problem and understand that, my hard disk file system is FAT32, which can only copy max 4GB single file size

 

I was thinking without losing my data, how can I change the file system, so that, I copy more than 4GB sized single files

Then I come across the following commands in Windows

1) chkdsk : Check disk

2) convert : Convert disk file system

 

chkdsk command

Syntax

cmd> chkdsk volume_letter: [options]

Example

Checks for disk errors and fix it

cmd> chkdsk I: /f

 

convert command

Syntax

cmd> convert volume_letter: FS:NTFS [options]

Example

Convert volume from FAT to NTFS in verbose

cmd> convert I: /FS:NTFS /V

 

Possible Errors with solutions

Insufficient Memory

Reason

Nearly 4 GB files in existing FAT32 system

Solution

Move the files to local drive, do chkdsk and then convert
