Hello,
My issue with my external hard drive is the following: how can I recover the data when it is riddled with bad sectors?
I tried to fix it with CHKDSK but nothing worked.
In this case, I would like to isolate all the bad clusters in order to then be able to copy all the now accessible data, and then transfer everything to a new hard drive.
If I simply try to copy all the data, it gets stuck on the bad sectors and nothing progresses, whether with supercopier or any other alternative or more advanced copy manager.
Thank you for your response.

If you want to try to recover data, you can use Recuva:

Very efficient and it's saved me several times already :D

I didn't say that I wanted to recover deleted data (if you read carefully), I'm talking about defective sectors, therefore inaccessible, so even Recuva wouldn't be able to do anything, so that's not the goal I'm looking for...
Hello.
To my knowledge, only a "low-level" formatting allows for the isolation of defective sectors.
It is also recommended to use the software provided by the hard drive manufacturer to perform this operation. (Samsung, Hitachi, etc.)
So in your case, it is highly likely that you will have to give up on some of the files that are blocked by these sectors..

Yes, but I need to recover the data, so it's not good. I want to isolate to recover better, you understand?
The goal is not to create a brand new hard drive with bad sectors isolated, but to be able to correctly recover the readable data. If you start the copy, it gets stuck on the bad sectors/files and doesn't progress.

Yes, I understand well. But unfortunately, having already faced the problem, I had to identify (as best I could) the files that were blocking during the copying process and mark them as not usable. (Then, back up all of those that were recoverable.)
If a proper chkdsk cannot do anything, your only alternative will be formatting. (Even though I understand that it's mainly a way to recover the blocked files that matters to you, I hadn't found another solution than low-level formatting.)
