Then "they" don't know what was on the hard drive, but "they" do know that something was on it. Who owns a sandblasting machine? However, I'm sure most of us agree that sheer force is more effective than nerdy software. You wouldn't make notes on paper illegible with an eraser, you would first tear up the paper, then burn the shreds and grind the ashes in a mortar and mix the ashes into the dog food. For HDDs the Italian mafia probably uses pizza ovens. So it looks like an accident to the public prosecutor's office if the hard drive got into the pizzeria's pizza oven.

The first step is owning a company, this is possible: https://en.wikipedia.org/wiki/Crypto_AG The second step, which concerns your counter-argument, is possible by switching from CMR to a well-developed SMR-like process. Who really knows what efficient writing methods are available today? Even if it's probably just a silly fantasy with HDDs, it's not far-fetched with SSDs. The advantage of SSDs could be that the data is probably lost relatively quickly if they have not been supplied with power for a long time.
