My flash has password protected and I do not know password. Is it possible, to crack password in some way?
Short answer: No, since neither me nor you know how the device operates inside.
Long answer: This requires a lot of knowledge on how this specific device implements the claimed
Enterprise-Grade Security. My best bet would be, most of users here don't know that, and Kingston won't divulge the "commercial secrets" of how they implemented this "security".
That said, my strong belief is that there are weaknesses (poor cipher implementation e.g. leaking key data on flash), debug backdoors (specific commands that e.g. reset the retry counter, upload arbitrary firmware, or anything else -- those are always there), and other nasty things lingering in the device. We simply don't know about them, thus we are unable to exploit them to get you access to what's on the drive.
So to sum it up: for you/me this is probably not possible as we lack knowledge on the device operation. For an abstract attacker -- yes, this may be possible.
NB. If the drive is yours, how come you don't know the password?.. ;-)
