There are times when you plug in an external hard drive or a flash drive, then see a message on Windows saying: “The file or directory is corrupted and unreadable.” This usually means that you may be unable to open the drive or even access the files on it. This can be quite problematic especially if you have a lot of important files on that drive.

While this problem can be quite a bother for most people, there are still several things you can do to fix it. In this article, we are going to focus on the symptoms and causes of “The file or directory is corrupted and unreadable”, as well as some effective solutions to this error and how you can access your files.

Part 1. Symptoms of “The file or directory is corrupted”

Before we get to the solutions, the following are some of the symptoms of this problem since it may present in different ways for different versions of Windows:

  • The file system on the drive could be a RAW file system which explains why you are unable to access the drive.
  • You may also not be able to access the drive when you see “The file or directory is corrupted and unreadable” error and you may therefore lose some of the data on it.
  • You may also see the “H:\ is not accessible” message popup when you try to open the drive (H is the drive letter of the drive you are trying to access).

If these are the things you experience when you try to open the external storage device, keep reading for the best way to fix the problem.

Part 2. Carry Out CHKDSK to Check and Repair Errors

CHKDSK is a command tool in Windows that allows you to check for disk errors. Once it detects the problem, this tool can easily fix the issues. Usually, this tool will find and fix the problems like directory errors, lost clusters, cross-linked files, etc. Follow these simple steps to do it:

  1. Click on the Start button and search for “Command Prompt”. When the results appear, right-click on it and then select “Run as Administrator”.
  2. When a warning message appears, tap on “Yes” to allow it to change the computer.
  3. Now, in the command prompt box that appears, type in “chkdsk /f h:” without the quotes and “H” represents the drive letter for the unreadable drive. Hit “Enter” on your keyboard and the process will begin automatically. Depending on the number of files on the drive, the process may take a while.
  4. Command prompt will let you know if the process has been successful.

Part 4. Possible Causes of “The file or directory is corrupted”

It is also important to understand some of the reasons why Windows may be displaying this error. This way, you can easily avoid the problem in the future. The following are some of the main causes:

  • An MFT (Master File Table) or FAT (File Allocation Table) error may cause the drive to be inaccessible.
  • If the USB, memory card or external hard drive is infected with a virus, you may not be able to access the drive and Windows will display the “The file or directory is corrupted and unreadable” error.
  • The drive may also be corrupted because of damage to the drive itself or bad sectors within the drive, making it completely inaccessible.
  • This problem can also occur when the external storage device is not removed from the computer properly. You should always unplug a removable drive from the device safely to avoid these problems.
