The whole point of having a password that is any good is so you CAN'T get around it. I'm guessing the memory stick is encrypted in some way, in which case there is no way to not enter the password and get to the data unless you created some sort of back door like a global admin account to use.
If the memory stick is encrypted, I doubt any software to retrieve data will help, unless it has the encryption hash, it will see the data on your stick as random giberish. From checking on the device Tigsounds recommended, it looks like it's used to recover DAMAGED drive info, not encrypted info.
