Convert USB/Hard Drive from FAT32 to NTFS in Windows
Before you begin following the Process to Convert USB or Hard Drive from FAT32 to NTFS, to be on a safer side it is better to take back up of all data from the Hard Drive or USB. However there is chance of less risks of corruption or data loss during conversion.
Close all open programs or files if they are running from the hard drive or USB which you want to convert.

Start Command Prompt (CMD) with Admin Rights in detail Click on Start button > All Apps > Windows System, right-click Command Prompt and then click Run as administrator If you’re prompted for an administrator password or confirmation, enter the password or provide confirmation.
In the Command Prompt, type convert drive letter: /fs: ntfs and press enter, (in my case I want to convert drive J: so I have typed convert j:/fs:ntfs).
In the Next screen you will be asked to type the current volume label of the drive (you should enter the existing name of the drive or else the conversion process will be aborted).
That’s it after entering the label name the conversion process will start and once it gets completed you will get a message in command prompt saying Conversion Complete as you can see in the above screenshot.
