|Sorry, but I think even a professional data recovery service could recover the data only with great difficulty, if at all. You can have security or easily recovered data but you can't have both.|
Many people use such drives to transport data that must not fall into the wrong hands. Security dictates that such data must be at the least very difficult to recover without the password. Preferably the data should not be recoverable at all, and that may indeed be the case. Locking a user out after repeated wrong passwords is a reasonable security measure.
This should not be anything more than an inconvenience to the rightful owner of the drive. Normal accepted practice would be to have the data stored on a local drive which itself would have at least 1 backup copy. Best practice would require 2 or more backup copies. For valuable data nothing less would be acceptable.
Flash drives are the least reliable of modern storage media. On top of that there is the possibility that the drive may be lost, stolen, physically damaged, passwords lost, etc. They should be used primarily as a transport media.
