What about Windows Reset?

Windows 10 includes its own reset options, which erase the drives relatively effectively. Although we would continue to recommend using third-party software such as Eraser, the Windows reset and formatting method is still effective if you take a few extra steps. To make sure that your data can not only be deleted but overwritten and not restored, follow the instructions to reset Windows. Then fill the drive with data. You can do this by copying movie files, game installations, or other items that are especially large – hundreds of megabytes or several gigabytes. Copy and paste again and again until the drive is full. Then put it back again.

The drive should be clean enough to dispose of.

Destroy the drive physically.

An alternative step to the above-mentioned digital data removal method or a secondary step if you want to double-check that your data can not be recovered. Everyone should physically destroy the drive.

If you are of the practical type, you can drag the hard drives (the actual hard drives that hold the zeros and your data) and grind the surface until they look like a dimple and crater. Another option is to pull a rare earth magnet, such as a neodymium magnet, over the drive plate. That deforms it and makes all data unreadable.

You can also drill holes in the drive if you do not want to bother removing the case.

There are companies that professionally destroy the device. Drive for you while you watch as well. Think "it will melt", but with a much larger mixer.
