Hi,
I have a 500gb exFAT format external HD which stored my photos and some camera raw photo.
However, I cant copy or backup those files to my pc since it shows a error message cant read from source or disk.
But the those files can be found in the explore.
So now what can I have to do with? I want my files back

Have you tried to copy your files using TestDisk ?
TestDisk, select the disk, Advanced, select the partition, List, select your files, copy them.
If it doesn't work, run PhotoRec.
