EaseUS Data Recovery Wizard Professional is very useful. Since my Windows 10 re-install I cannot read the data on my older external, I'm recovering some external hard drive files before formatting it to use it again. Here are some stats:
Total Found: "Deep Scan completed. Found: 889,491 files (1,610.13 GB)"
Recovering: "Selected: 792938 file(s), 747.96GB"
Selected: Lost Partition1(NTFS) files: (793,010)
This is just step one of three!
