There's no desparate state secrets involved, just confidential personal info about clients. Owners wouldn't spring for new drives just to give 'em away - not good business sense. Unlikely that security experts would be involved - just safeguarding clients against curious amateur with a bit of IT knowledge.

Thanks guys; I appreciate your taking the time to help.
