I wonder how well that hammer thing worked.
It's beautifully effective for drives because they are high speed high precision mechanical devices, but even if you broke up the circuit board the chips were soldered to a guy with a soldering iron and some know how might still be able to get it back together again. Looking at that cell to gate progression posted earlier it sounds like unless you are able to actually destroy a given gate you don't destroy access to a give chip. If you were able to access the internals of the chip that might not be a barrier.
Too many electrons are easy to find though. Maybe get some rubber gloves, one of those hand held stun guns and zap the board parts a few times after (or before) you're finished hammering. It could be fun and sparkley. This also provides opportunity for some memorable conversations with management. " ...It's these SSDs boss. They're just really hard to erase when they fail. I'm afraid the department is going to need it's own Vandegraff generator..."
The blue smoke wants to be free.
