Converting the USB File System to NTFS
The simplest way to change the file system on a USB drive, especially if it already has files on it, is to convert it. This method does not delete the existing files. If the files being converted are large or many, the process might take a few minutes. Things will go alot faster if the drive is empty because you moved them temporarily to a different location. To convert the drive follow these steps: 1. Connect the USB drive to the computer and make a note of the drive letter assigned to it 2. Open a command prompt by clicking on: Start > All Programs > Accessories 3. At the command prompt type: CONVERT F: /FS:NTFS (where F: is your USB drive letter )
