You are nowhere near paranoid enough.
The cost is in the order of $100K for someone in the Western world
using commercially produced equipment, doing the work on a contract
basis. Thus in the Western world, the return on scanning a hard drive
would have to exceed $100K worth of financial benefit or the
overthrow of a Government.
For someone in (insert industrialising-country-of-choice here), the
return on investment might only have to cover the food they have to
eat while operating the borrowed or stolen equipment, along with
enough to buy the neighbour's farm.
When worrying about the risk of exposure of data, you have to think
who could benefit the most from that data being exposed. A credit
card number worth $5000 in Australia would perhaps buy you a year's
supply of petrol, or a couple of nice black suits and matching ties,
or a stolen gun. That same number in (for example) China might be
enough to acquire a small real estate empire and settle into a life
of financial stability.
