Linux - Convert FAT32 to NTFS without loss data [migrated]

view story

http://stackoverflow.com – 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. Thank you very much. (HowTos)
