Use GiliSoft Data Recovery when Windows says you need to format the drive before you can use it. Scan the drive first to recover files before formatting reduces recovery chances.
1. Do not click Format if important files may still be on the drive.
2. Launch GiliSoft Data Recovery and select the affected drive.
3. Run the scan and review recoverable files before making changes to the file system.
4. Restore important files elsewhere, then decide whether repair or formatting is still needed.
