Quit spreading FUD. The cost of building a subverted drive isn’t worth the time or money for general distribution in the economy. You need a high percentage of the drive’s physical capacity dedicated to spare space to get a decent chance of catching useable data in “reallocated” space. Of course your competition can just sell a higher capacity drive and put you out of business.
