chkdsk is not available for raw drives

When your SD card, USB, or hard drive is not performing properly and showing errors, it could show signs of corruption. One reliable way to check and fix the corruption is to run the CHKDSK command. But if the CHKDSK cannot check the drive and returns the error message “CHKDSK not available for raw drives,” what does it mean? To find out why you got this error message and to overcome this problem, continue reading the article.

What does "CHKDSK is not available for RAW drives" mean?

In simple terms, the error “CHKDSK is not available for RAW drives” usually occurs when the command CHKDSK cannot be used on the drive with the RAW format. Many Windows commands don't work on RAW drives because Windows cannot access that drive. This is the reason why the error code usually occurs.

In the below write-up, we guide you with hassle-free solutions on how to fix the CHKDSK error code easily.

Why Does the “CHKDSK not available for raw drives” Error Occur?

To understand why this error occurred, you must know how the chkdsk command works. When you run the chkdsk command, it checks the logical and physical errors in the file system and the data in the volume.

But when your drive does not have a proper file system and has turned RAW, CHKDSK will be unable to locate the file system and its data in the volume. Therefore, you will get a return message stating, “chdksk not available for raw drives.”
