I purchased a broken hard drive. I copied some of my movies on it. It is broken now. I want to send it back to the factory.
I wanted to permanently delete all my files with "Sdelete" secure tool. This would take 20 hours to overwrite 4TB with random bits. My drive crashes every 10 minute, so I cannot use the command line tool.
What alternative are there to clean my data. I know formatting is not safe?
