Why do I get file or directory is corrupt or unreadable error?

There are quite a few causes that can lead to a corrupted and unreadable partition. Let's take a look at some common reasons behind the error.

  • USB disk is not safely ejected: File system tends to get corrupted if USB drive gets disconnected before Windows finishes reading/writing data on it. Besides, a sudden system shutdown or power cut can lead to a similar situation. Windows provides the function to safely eject USB drive to help us prevent corrupted file system: click the icon "Safely Remove Hardware and Eject Media" before removing external disks.
  • Virus/malware: some virus can destroy vital part of file system, for example, BDR, the MFT of NTFS file system, or the File Allocation Table of FAT file system. The consequence is inaccessible partition.
  • Improper operations: some improper action can also damage a partition, for example, partition resizing process gets interrupted; 4K alignment fails to complete; error occurs during converting file system type, etc.
  • Bad sectors: bad sectors are no longer readable or writable, and they can occur on any area of your disk. If the disk space where file system is stored contains bad sectors, then Windows cannot access it, resulting in an inaccessible partition.
