I was using defraggler to optimized my External HDD after first fill with data, the optimize option showed it will zero fill empty space of HDD, and I clicked yes. But then the progress stuck on 68%, I restart my PC, now Window ask me if I want to format the HDD, file system shows raw under disk management in Win10. And Defraggler mistaken External HDD as SSD, maybe that’s why it ask if I want zero fill in the first place.
Is there anyway I can save my data from the disk?
I remember normally I can stop defrag process, what went wrong?
