I have the exact same problem. My drive is coming out as a RAW format in disk manager and I tried test disk to. DId a quick scan with test disk but it found no partitions. I tried the recovery software that comes with test disk but it gets my files but there’s all messed up names and its just useless. What can I do? Help plz.
