Converting FAT32 to NTFS on Transcend 1TB External Storage

If you don't want to use a converter or are unsure about the reliability of them, I would suggest getting an external drive and backing your files up to it. Then you can reformat your other drive. Once the reformat is complete, simply copy your files back to it.

Honestly, last time, after attaching my external hard disk to a PC, I do find my external hard disk has RAW file system and cannot be accessed, too.
