Ran Testdisk 7.1 on the selected disk which resulted in No Partitions Available from the Analysis and also from the Deep Scan. Also ran CrystalDiskInfo which resulted with Health Status Unknown on the drive. The log file is almost 4 GB and wont attach herewith. Screenshots attached. Any next steps to recover the data on the drive?

CrystalDiskInfo probably failed to read the SMART status...
If Testdisk.log file is so big, it's probably because it's full of read error message.
In this case, there is nothing you can do. You may have to contact a data recovery company.
