It is... It's literally a preconfigured option on the dban selection list.
Source: My memory... but if that's not good enough, here's wiki too.

It's an option, but not the default. It takes forever to run, so someone using it is being very intentional.
It's also considered wildly overkill, especially with modern drives and their data density. Even a single pass of zeros, the fastest and default dban option, wipe data at a level that you would need a nation state actor to even try to recover data.
Okay so what you think is wildly overkill, is about 10% of the effort some organizations go through to make sure data is not restoreable.
My org shreds discs entirely with a mechanical grinder, so I'm well aware of overkill.
Multiple overwrites being unnecessary isnt really an opinion. Here is the company that owns dban agreeing with security orgs like NIST, that anything past 1 write is unnecessary. .
I think the issue comes down to whether the org in question does that 7 passes consistently on all discs, or if it just so happened to start that policy with those that had evidence on them.
No? If 1 is sufficient, any additional shouldn't matter in any considerations at all. Could have simply been somebody who hit the preset on accident.
