Thank you very much, I’ll be checking this out later

I would recommend using ddrescue. It can copy block by block, can skip over slower or error prone regions to prioritize good sectors.

I used it to pull 2tb from a dying drive. It was able to pull 1tb in about 4 hours, and took about 2 weeks to clone the remaining 1tb. But it successfully pulled all data with no errors in the end. Saved my 8tb raid array.
