"NTFS read-only driver enabled"

Hello
I'm trying to set up a backup operation to back up the video files on my NS2 to the external usb hard drive I have connected to it, in 'Host' mode.
After having made the necessary selections and clicking on "Accept", I get this error:- "Backup command failed: NTFS read-only driver enabled". Sure enough, the usb hard drive is formatted as NTFS.
Does this mean that before I can use it to back up I must format it as FAT 32 (having first connected it to my PC then re-connected it to the NS2)? Or is there another, perhaps preferable, way?
Guidance would be much appreciated. Thanks.
