What to do if my Dell Desktop displays 'Sector Not Found'?
- SSamantha SantosSep 12, 2025
If your Dell Desktop displays 'Sector Not Found', the operating system cannot locate a sector on the hard drive. You may have a defective sector or corrupted File Allocation Table (FAT) on the hard drive. Run the Windows error-checking utility to check the file structure on the hard drive. If a large number of sectors are defective, back up the data (if possible), and then format the hard drive.
