I have 1 TB hard drive, and I want to delete sensitive data from it. What I have tried:
- Format the hard-drive "deep slow format" from CMD command.
- I tried c-tools.
- Also I tried cipher built in tool that came with windows 10.
But nothing worked. I also used cipher tool 3 times to be sure it write random numbers on my deleted files but that doesn't work.
With normal recovery tool I can backup the same data again!
Is there any good command to rewrite on these deleted files so no one can recover them again?
