Is the consumer market for second-hand drives large for them to be concerned about it? I always thought that >99% of people keep the drive their desktop/laptop came with and junk/sell/donate the whole thing without ever turning a screw. The number of people who are savvy enough to know about SSD, be willing to upgrade a drive, willing to shop for a used one vs a new one from Dell/Amazon/Newegg, and still be able to be duped might be a pretty small market.
