Convert From FAT32 To NTFS Without Losing Data

I have had a 1TB external HDD that I bought a while back that I formatted the other day. After I started copying all of my data to it, I realized that I accidentally formatted it over to FAT32 and it only had 430GB of the 1TB that I could use because of FAT32 restrictions. But I already started copying the data over and didn’t want to have to restart it. I found out there is a way to change the format of a HDD without loosing data!


NOTE: Although this method worked perfect for me, I would suggest you backing up your data first just in case!

  1. Go to Computer, and note the name of the drive whose file system you wish to convert.
  2.  Click on Start.
  3.  Type cmd in the search bar if you use Windows 7, Windows 8, Windows 8.1 or Windows Vista. If you use Windows XP, click on Run and then execute cmd.
  4. Execute “chkdsk h: /f ” (without quotes) where H is the letter of the drive to undergo conversion. This checks the drive for errors and fixes them automatically.
  5. Execute “Convert H: /FS:NTFS” (without quotes). H is again the letter of the drive to be converted.
  6. The command prompt will start the conversion process and after a few minutes, CMD will say that conversion was successful.
  7. You can check it in the properties of the drive through right click<Properties.

A viola! You know have a drive that is NTFS with all your data still on it!
