My USB drive suddenly stopped opening and Windows kept asking to format it. I searched online and learned how to format PenDrive using CMD, which helped fix the corruption and made the drive usable again. But after formatting, all my important files were missing, so I tried the SysInfo Removable Media Recovery Tool to get them back. The software was simple to use, scanned my USB, and showed the lost files so I could recover only what I needed. If your flash drive also becomes unreadable, repair it first and then run recovery after pendrive format cmd to stay safe. It really helped me restore my data without stress.
