Was it probably a IronKey? They had a Homeland Security grant, I've used one then.
To me software had some advantages. Easy backup of the encrypted data without a dependency to the hardware. IIRC this was somehow solved on the IronKey. Not a black box for the user which have to trust.
My main problem with a software solution for me is the entry of the password which I have to do on a probably compromised computer.
The original IronKey (later sold to Kingston) seems to have be cracked.
A team / company called Unciphered managed to break a IronKey in a attempt to offer such a decryption to Stefan Thomas who had 7002 bitcoin on this key.
This was then worth then 235 million dollar (now >500 million), which is of course a VERY strong motivation. [1]
The Lenovo case of course seems not to be bad implemented security but no security at all, especially if they advertise with encryption, which I found on a Asian Lenovo website where still there are still some specs of the key [2].
A good method if you want to damage your reputation.
