CHKDSK is Not Available for RAW Drives? Free Fix in Windows 10/11 Here!

📚 Seeing the error “CHKDSK is not available for RAW drives”? This guide explains why it happens and shows you how to fix a RAW drive or partition for free using built-in Windows tools in Windows 10 and Windows 11.

When it comes to repairing file system errors or fixing a drive that’s detected but inaccessible, CHKDSK is often the first tool that comes to mind.

However, if the affected drive has become RAW, CHKDSK won’t always work. Instead, you’ll see the following error message:

“CHKDSK is not available for RAW drives.”

Author’s Note: 🤔 I don’t say CHKDSK never works on RAW drives because, in my own testing, it successfully repaired my SanDisk USB drive that had become RAW after I accidentally unplugged it during a full format. This suggests that in some cases, where the file system is only partially damaged, CHKDSK may still be able to restore the drive. However, if the file system is severely corrupted or completely missing, you’ll typically receive the “CHKDSK is not available for RAW drives” error instead.

Why “CHKDSK is not available for RAW drives.”?

CHKDSK is designed to scan and repair drives with a recognized file system, such as NTFS or FAT32. However, when a drive becomes RAW, Windows can no longer identify its file system. This usually means the file system is corrupted, damaged, or missing.

Because CHKDSK has no valid file system structure to examine, it cannot perform a repair and returns the message:

“CHKDSK is not available for RAW drives.”

This is also why **the drive can still be detected but becomes inaccessible** when you plug it in. The hardware connection is working, but the operating system cannot read the file system needed to access your data.

How to Fix a RAW Drive for Free in Windows 10/11

The most straightforward way to fix a RAW drive in Windows is through the built-in Disk Management tool. Here is how:

Step 1. Press Windows + X and open Disk Management.

Alternatively, you can press Windows + R, type “diskmgmt.msc”, and press Enter to open Disk Management.

Step 2. Here, you will see a list of all connected drives. Locate the drive marked as RAW.

Step 3. Right-click it and select “Delete Volume”.

Step 4. Once the partition or drive becomes “Unallocated”, right-click it and select “New Simple Volume”.

Step 5. Follow the New Simple Volume Wizard. Leave the default volume size unless you need a custom partition size.

Step 6. Then, assign a drive letter and click Next.

Step 7. Choose a file system- NTFS for Windows use, exFAT for USB drives, SD cards, and other portable storage.

Leave other options at their default settings, then, click “Next”.

Step 8. At last, check your settings and click “Finish”.

After the process is complete, the drive should appear in File Explorer again and be ready for normal use.

📢But Before Fixing a RAW Drive, You’d Better…

Formatting a RAW drive can rebuild its file system and restore normal functionality. However, it can also make existing files harder to recover afterward.

If the drive contains important documents, photos, videos, or other valuable data, avoid reformatting it immediately.

Instead, recover your files first. Use a reliable data recovery tool that can ***safely scan and recover data directly from a RAW drive without formatting*** it.

Once your critical files have been successfully recovered and stored in a safe location, you can repair or format the drive for normal use.

In Conclusion

The error “CHKDSK is not available for RAW drives” simply means Windows can no longer recognize the drive’s file system, so CHKDSK has no file system to examine or repair.

Fortunately, the problem is usually easy to resolve by recreating the file system through Windows Disk Management.

Before doing so, however, consider whether the files on the drive are still important. If they are, recovering your data should always be the top priority. Once the drive is reformatted, it will function normally again, but recovering the original data may become significantly more difficult.
