Safe Windows 11 file and storage troubleshooting order

  1. Back up irreplaceable data before repair.
  2. Record the exact error, path, disk and file-system state.
  3. Separate Explorer display, permissions, file system and hardware.
  4. Test one small non-important file first.
  5. Use supported Windows storage and repair tools.
  6. Format, initialize or delete volumes only when data safety is proven.

Never initialize, format or delete a volume that may contain needed files. Keep verified backups on a different physical device.
