CHKDSK is an old yet effective disk repair utility that has been integrated into nearly every version of Windows. However, when you run it, you may encounter a frustrating error message:
"The type of the file system is RAW. CHKDSK is not available for RAW drives."
When this happens, the drive becomes inaccessible, and Windows may repeatedly prompt you to format it. But don't worry—this error doesn't necessarily mean your drive is permanently damaged or that your data is gone. Here, we'll briefly explain why this dread error appears and show you how to safely repair a RAW drive. Stay with us!
Overview of CHKDSK Is Not Available for RAW Drives
What Is a RAW Drive and Why CHKDSK Cannot Run on It?
Before a storage device can be used, it must have a file system—such as NTFS, FAT32, exFAT, or APFS—created on it. If your drive's file system is missing or corrupted, the operating system will not be able to access it. In this state, the drive is referred to as a RAW drive.
CHKDSK, on the other hand, relies on a valid file system to repair disk errors. This is why you may see the message: "CHKDSK is not available for RAW drives."
Common Causes of a RAW Drive
Several factors can cause a drive to enter a RAW state, including:
- Virus or malware infection
- Abrupt ejection during formatting or file transfer
- Physical damage or wear on the drive
- Improper removal of external drives, sudden power loss, or system crashes
- Corrupted partition table or MBR
- Driver conflicts
Now, let's take a closer look at how to fix the 'CHKDSK is not available for RAW drives Windows 10' issue!
How Do I Fix CHKDSK Is Not Available for RAW Drives?
Step 1: Check the Drive for Physical Problems
So, how can you fix the "Check Disk not available for RAW drives" error? On some occasions, RAW drive errors are caused by faulty cables, ports, or hardware failures rather than file system corruption.
Start by ensuring the drive is properly connected to your computer. Inspect the USB or SATA cable for any visible damage, and try using a different port or cable to eliminate connection issues. It's also helpful to connect the disk to another Windows machine to see if it's detected. For hard drives, pay attention to unusual noises, such as clicking or grinding, which may indicate mechanical failure.
If physical damage is suspected, stop using the drive immediately and seek professional assistance. Any DIY repairs, such as formatting or running disk health monitoring tools, could potentially cause further damage.
Step 2: Rescue Data from the RAW Drive

Tenorshare 4DDiG is a powerful data recovery software, especially effective at extracting files from drives that are unreadable, inaccessible, or in a RAW state.
