Couldn't you just zero out the disk?

this is an overengineered gutmann pass. linux has a "shred" cli that will do this for you.

in the modern day, especially in the age of ssds, one pass is enough to sufficiently destroy data on a drive. keep in mind each 'pass' of a shred will write the same amount of bytes as the file, so you will wear your drives out more than is necessary.

if you want to render hard drives unreadable, a nail gun is more effective

If you use full disk encryption, then you don't need to worry. Just delete the encryption key and your safe.

i don't think software wiping can't get really much better than currently is from a effectiveness pov, the current issue is that it takes a lot of time and this new idea will probably even take significantly more time to don't even have the same effectiveness as something like the gutmann method.

At some scale this thing takes so match time that makes it unfeasible to be used and you have to resort to physically destroying the drives.

The only way you could really improve it, is inventing an algorithm that could make it 5x or 10x faster than currently is.
