Except that the analogy is wrong: it’s quite easy to destroy the information. In practice, writing random data to a modern hard disk leaves it unrecoverable.
So:
Why did the idea that hard drives (a completely different form of data storage, something specifically designed to retain data across a wide range of conditions) are hard to erase make you think that it was hard to erase data from brains?
Now that you know that it isn’t hard to irrecoverably erase hard drives (even though they’re designed to retain data), how does that affect the analogy with brains? Why?
The weight of subject-expert opinion appears to be that it’s not recoverable unless and until you can show it is, in fact, recoverable. If you’re asserting otherwise, the first thing you’d need would be a counterexample.
I note also you’re supporting an expert opinion that agrees with you and denying an expert opinion that disagrees with you … when they’re linked opinions from the same expert.
No, I’m pointing out that the ‘expert opinion that disagrees with me’ doesn’t, in fact, disagree with me. The quote you yourself provided does not support your position.

The analogy is not wrong. As you quote, it takes multiple passes deliberately trying to destroy the information to remove it.
Or an external degaussing magnetic field. Or heat. These methods make the hard drive unusable, but they reliably destroy information.
