Linux – Convert FAT32 to NTFS without loss data


I have an external USB hard disk (300GB) in FAT32. The question is how can I convert the type FAT32 to NTFS without loss my data. I have 250 GB of data stored in my disk.

I was trying to do that in windows with Acronis and the native command windows convert, but neither can do. I think maybe was for the big size of data.

I hope someone can guide me a little.

If you want to keep the data safe and do serious filesystem manipulation (which converting the FS certainly is), then first make a backup. Then test the backup.

Next you have three choices:

  1. Boot windows (e.g. use someones computer) and use convert Driveletter: /fs:ntfs. (See for more details).
  2. Reformat the drive. You already have a known good backup and this is likely to be the fastest option. Then restore the data.
  3. Find some utility which lets you convert under Linux. I never heard of one though and some quick googling did not find any.
