This device feature 256-bit AES native encryption, looks like a little bit hard to overcome especially if you don't remember how many characters, numbers, letters or sign are used. This doesn't mean, that is impossible.
EDIT : Looking at many USB encrypted-drive, maybe, there is a simple walk-around : Many usb keys, have a limit of password insert attempts, usually 4 or 5, after those, the key format the drive... but remove also the AES encryption and doesn't shred the files, then you could recover with a program like Ontrack easily your datas. BUT BE CAREFULL... this operation is risky because the USB drives are not all the same there are some as IRONKEY, that shred totally all datas, then if you want to try is at your risk.
