This removable drive must be formatted with a file system before you can use it. Because this drive is large and currently allows quick removal, none of the built-in file systems can format it. Disabling quick removal for the drive will allow the NTFS file system to format it.

To avoid corrupting the drive when you remove it, always click the Safely Remove Hardware icon (the circled icon in the graphic below) in the notification area, and then click the device name.
