yes, do 2 full scans. If these are OK, then put drives inside a safe with 2m thick concrete walls. Build a new computer using all certified, guaranteed hardware that will not fail. Call the power company and get a dedicated, filtered, power supply that has multiple fail-safes built in. Clear your Neighborhood of people so there is no chance of anyone interrupting the data transfer. Stop all Wi-Fi, cellphone data in the area to make sure there is no interference. make sure there are no magnets in the immediate area, 1KM to be safe. Remove ALL CATS from the surrounding area - Cats are very bad for computers, laptops especially. make sure there are no glasses of wine close. These are also a natural enemy of computers.

Once you are certain the data transfer will work, test 3 times by cloning your data then restoring it. do a binary file comparison to make sure data is the same.

If this is ok, throw away your whole system and build an identical one - you can't trust it now you have used it 3 times.

backup your data, encase in concrete and bury in your backyard. Make a sign 'NO HARD DISKS BURIED HERE' to trick any criminals digging it up and stealing your drives.

follow these simple steps and you can be slightly ahead of if you just use your perfectly fine drives.

It would be ironic if for some reason your PC crashed and you lost all your data, after spending 2 years drilling down every little possible 'what-if' and never actually just did the backup.

Why did the graph line stop between 357G 429G but the HDD is 1TB? Was the scan complete at 1TB without errors?

isnt smart data good enough for that?

I put 300GB on this HDD and it didn't corrupt

any test for comprove fake no delete or modifify my files inside hdd?

Are you a bot?

being legit is only part of the equation. The equation is σ (n) ≤ Hn +ln (Hn)eHn. Once you solve, you know for certain your HDD is fine.
