I have 4tb wd external hard disk purchased one month before.I accidentally click on format hard disk become 0 byte. I use some recovery software but no data show. How to recover data.
Hello friend, you can try to use winhex to see the hex data and see if all sectors are 0000， if 0000, cannot recover, if not 0000, there’s a chance.
