<i>While we know the crypto design is a fail, because all the encryption related data is stored on the drive itself,</i>...<p>I don't see why this makes it weaker, could someone explain?<p>The only apparent weakness I see from this page is that the secret key is a 4-8 digit number, meaning that the device could be realistically brute-forced by someone who knew the encryption algorithm.
Regardless of vulnerabilities, from a data safety/recoverability point of view it never seems like a good idea to me to use an encryption system that doesn't have a documented on-disk format.
