When an external hard drive becomes unreadable, the notification “The file or directory is corrupted and unreadable” may occur in Windows 10/11. This article provides practical options for resolving the problem and restoring data access. In addition, how to recover data from damaged or unreadable disks.
External hard drives and USB flash drives are often used by computer users to enhance available storage space, store a variety of data, back up important files, and transfer files between workstations.
Directory is Corrupted Use these methods:
FAT or MFT corruption
The file systems now used on Windows PCs are NTFS, exFAT, and FAT32. All of the information, including file size, creation time, and access permissions, is saved in a file called the MFT (Master File Table), which is part of the NTFS file system. Like MFT, the FAT file system features a FAT (File Allocation Table) that tells the operating system where each file is placed. When the FAT or MFT is corrupted, the system is unable to access data from the NTFS or FAT partitions.
Malware or virus infestation
When you connect and unplug storage devices from different computers, an external hard drive may become infected with spyware or a virus. Malware or viruses have the power to distort partition information, erase crucial data without notice, corrupt operating systems, and even infect other connected devices. When the file system is broken, you may see an error stating that the files or directories are corrupted and unreadable.
Physical harm
The “disk not accessible” error message may also appear if the attached storage medium contains faulty sectors. Unusable and unwriteable, faulty sectors are forever damaged. You cannot access the data if your partition’s data, including the file system, is placed in faulty sectors.
Wrongful dismissal
It is always advisable to safely delete linked storage media from your computer. This is because unplugging an external hard drive or USB flash drive while it is in use—for example, to transfer or retrieve drive data—can impair the file system and result in an error message claiming that the file or directory is corrupted and inaccessible.
Repairs for ruined and unreadable files and directories
Run the CHKDSK command.
CHKDSK is a system tool and command that is used to check the file system integrity of a volume and attempt to repair logical file system faults. As a result, if the malfunctioning file system renders the disk useless, you may use the chkdsk command to repair it.
- After selecting the Start menu, put “cmd” into the search field.
- When Command Prompt displays, right-click it and select “Run as administrator”.
- Enter the following command, replacing “h” with the drive letter of your choice.
- chkdsk /f h: waiting for the stages to finish.
- If the file system is substantially damaged and the chkdsk command is unable to restore the inaccessible drive, it can be repaired. If it says CHKDSK isn’t compatible with RAW drives, move on to the next solution.
RAW drive repair
As previously stated, the file system can be RAW if a file or directory is corrupted or unreadable. You can check this with Windows’ drive manager, Disk Management. Furthermore, if the CHKDSK command is executed, it indicates that the disk is RAW and displays that CHKDSK is not available for RAW drives.
- Download, install, and run Webbyacad data recovery tool for Windows on your computer.
- After connecting the inaccessible disk, select the RAW disk Recovery module from the main interface.
main interface - Select your unreadable media from the list of detected disks or partitions.
