You can use TestDisk recovery for this. Get TestDisk livecd or Ubuntu Live CD with TestDisk. Copy it to the flash drive and make it bootable.

After, you can just delete your NTFS partition. Then when you want to recover it, use TestDisk livecd. More information here: https://askubuntu.com/questions/171163/how-to-recover-a-deleted-ntfs-partition-with-data

This will only work if you do not write anything nor create any new partitions on the disk.
