If you’re talking about hard drives you’re way way behind on the state-of-the-art on data recovery technology. It’s a magnetic materials science\signal processing problem. You almost have to physically destroy the drive to prevent recovery. One friend who stayed in the field said “drives have to be turned into slag to prevent recovery.” I am sure that’s somewhat of an exaggeration ! I helped develop such systems back in the DOS\Windows 3+ days. In those days it was a tedious labor intensive problem but a doable problem. I would be shocked if there aren’t commercial recovery systems now available and easier to use.
A utility I have makes multiple passes of writing 0’s or 1’s or a random pattern of both. Each time additional pass is made to overwrite data, it becomes increasingly more difficult to recover original data.
Yes, it can take a few hours to finish. But democrats had nearly a month to wipe crooked software and replace it with honest software.
As soon as those huge blocks of votes for Biden were discovered at 4AM on Nov 4th, Trump should have ordered military to confiscate all Dominion machines citing foreign interference in elections. He had already issued an executive order for such action before.
Deal with law suits later.
