wd drive data is deleting but not opening

I have a drive "wd my passport" 1tb. I am connecting it on Ubuntu 20LTS.

I am not able to open any data, not even able to copy or move any data. While Coying ubuntu gives error of I/O.

But I am able to delete few files and folder which is not necessary.

Why is so?

I even tried ddrescue to recover ,but it's very slow, too slow.I lost my patience and got recovered 1gb of data through ddrescue and then deleted the .img file also.

I even tried a powershell script in windows 10 , script was developed by davor josipovic.But copying ecah file separately is hard job and time taking.

I just want to know why deleting files is easy and accessing files hard? What can be the solution to get files fastest and easiest way possible.
