I have had one amazing success story of data recovery with “Hirens BootCD”, under its Linux option, in the default boot mode. The drive was not even recognized under Windows most of the time. In fact, Windows mostly wouldn’t even boot if this (data) drive was connected.Test Disk reported nothing but read errors. Find and Mount found no partitions.
You can find the ISO for the CD here:

A description of what I went through is here-
I know the feeling of lost data all too well. I had given up on my “dead drive” when a friend turned me on to this CD. Besides multiple boot choices, it has dozens of freeware utilities on it which are easily accessed through a menu system.
Best of luck!
