I disagree. If they encrypted the data correctly, they know very well if 
it is secure or not. There are specific encryption algorithms and 
associated key lengths considered suitable for disk encryption. The most 
commonly accepted is AES with a 256-bit key.

It is chosen as such, because as of yet, no flaw has been found in AES, 
and a 256-bit key could not be brute-forced in any feasible time frame 
with current technology. In other words, when you finally brute force it 
10 or 15 years from now, the credit card numbers and SSNs will be useless 
anyway.
