I recently purchased a 5TB external hard drive to archive some important media files. After I copied around 2TB of data over to the new drive I realized that it came formatted out of the box in FAT32 and not NTFS. Since I had files that were larger than 4GB leaving the drive in FAT32 was not an option. I had already spent a considerable amount of time archiving files to the new drive and did not want to reformat the drive and start over. Since doing a non-destructive partition change in Ubuntu Linux is not possible I booted into Windows 10 and used the convert J: /fs:ntfs command to change the file system. For some reason this command did not work so I searched for a 3rd party utility software to accomplish the change. I found a neat little utility called EaseUS partition software that worked like a charm. EaseUS is free for home users.
