# How to fix “The File or Directory is Corrupted and Unreadable” error

This is a common error commonly encountered on Windows computers when the operating system cannot access data on the external hard drive:

E:\ is not accessible. The file or directory is corrupted and unreadable.

(Drive E:\ is inaccessible. File or folder is corrupted and unreadable).

You may get this error after trying to open something from USB. Or, depending on how your computer is set up, the error may appear immediately after inserting the hard drive into the computer.

This “not accessible” error can happen at any time, even if you’ve only recently used the drive. The beginning of the error message is the unreadable location of the data, so it could be E:, H:, K:, etc.

## Cause of “The File or Directory is Corrupted and Unreadable” error

There are several reasons why you might get this error:

• Drive is safely removed without disconnecting
• Malware has infected the drive: It is not surprising that you can infect your computer with viruses or malware when you download something from unofficial sources. This can lead to damage to connected external devices and prevent you from accessing your files.
• Physically damaged external hard drive: If the storage device is permanently damaged, you cannot access the stored information. Also, check the integrity of the hardware connection by looking for any damaged USB ports or cables.
• Corrupt MFT or FAT: The MFT (Master File Table) contains the file or directory type, size, creation or modification time, among other information. So you won’t be able to access your files if the MFT is corrupted or has problems. FAT (File Allocation Table) is a system similar to MFT and it is designed for hard drives. If the FAT is malfunctioning, it can also lead to the same error.

This error can occur on any Windows operating system. The steps below apply to Windows 10 and earlier.
