I have tried to follow the instruction step by step, but I find the result is different. I upload the log, so anyone can check and help me. Right now, I'm trying photorec to recover my data while waiting replies (2500 hrs left!).
Is it possible to repair my external hard disk in this condition?

Sorry if a bit difficult to understood, since english is not my first language.

Thanks for any help.

The output of your current partition strucur using partition table type Intel is "Read Error" only.
Using EFI GPT displays your partition table not correctly, but it displays your data.
Looks like, your file system is faulty.

I'd suggest to copy your important data first!
If you list your data, at the bottom of you screen, you'll find all the commands.
Target folder would be your testdisk folder.
If you'd like to change it, you can mark that two dots in the upper area of your screen and press enter.
You'll get each time one directory up until you'll get to your disk selection.
You can select another healthy disk or partition, where you'd like to recover your data to.
Please try to copy your important data first.
If you experience any problems, due to your faulty file system, please let me know.

Currently, I've no idea why partition table type Intel causes a read error and EFI-GPT works?
We should have a look after you were backing up your data!

can you give a step by step to recover my data? because explorer cannot open my hard disk at all, and recovery softwares are not working either.

If recovering the data is not possible, I want to continue to recover the hard disk without the data. I have backup of the other data in my laptop, and the rest of the files can be ignored.
