A RAW drive indicates that Windows cannot recognize the file system, often due to corruption or an unformatted state. To restore it to NTFS while preserving data, you must first recover your files using specialized software before formatting the partition. This two-step process ensures you do not lose critical information during the repair operation.
Understanding Why Drives Become RAW
Before attempting any fixes, it is crucial to understand why a drive appears as RAW. The "RAW" status means the operating system sees the hardware but cannot read the file system structure, such as NTFS or exFAT. Common causes include improper ejection of USB drives, power failures during write operations, bad sectors on the disk, or malware infection. In some cases, the Master File Table (MFT) may be corrupted, leading to this error state. Recognizing the root cause helps prevent recurrence after the fix.
Step 1: Recover Data from the RAW Drive
The most important rule when dealing with a RAW drive is to never format it immediately if there is valuable data. Formatting will erase the file system structures, making recovery much harder or impossible without professional tools. You need to use third-party data recovery software to scan the raw partition and extract your files to a different, healthy drive.
Start by downloading a reputable recovery tool like Recuva, EaseUS Data Recovery, or Disk Drill. Connect the affected drive to your computer and launch the software. Select the RAW drive from the list of available disks. Initiate a deep scan, which may take several hours depending on the drive size. Once the scan completes, preview the found files to ensure they are intact. Select all necessary files and save them to a location on your internal SSD or another external drive that is known to be healthy. Do not save recovered files back onto the RAW drive itself, as this could overwrite remaining data.
If you suspect physical damage, such as clicking sounds, stop immediately and consult a professional service. For logical errors, software recovery is usually sufficient. See our guide on

Step 2: Check for Disk Errors Using CHKDSK
After securing your data, you can attempt to repair the file system without losing data using the Command Prompt. The
chkdsk utility can sometimes fix logical errors that cause the RAW designation. Open Command Prompt as an administrator by searching for
cmd in the Start menu and selecting "Run as administrator."
Type the following command, replacing
X: with the actual drive letter of your RAW drive:
chkdsk X: /f /r
Press Enter and wait for the process to complete. If successful, the drive should reappear as NTFS in File Explorer. However, note that
chkdsk may fail on severely corrupted drives or return an error stating that the volume is not recognized. If this happens, proceed to the next step. Also, be aware that running
chkdsk on a physically failing drive can accelerate its death, so only use this method if you have already backed up your data.
Step 3: Format the Drive to NTFS
If data recovery was successful and
chkdsk did not work, you must format the drive to create a new NTFS file system. This will erase all data on the drive, which is why Step 1 was mandatory. Right-click the Start button and select "Disk Management" to open the management console. Locate your RAW drive in the lower pane. It will likely show as "Raw" or "Unallocated."
Right-click the RAW partition and select "Format Partition." In the dialog box, choose "NTFS" as the file system. Leave the allocation unit size as default. Ensure the "Perform a quick format" box is checked unless you suspect bad sectors, in which case leave it unchecked for a full format. Click OK and confirm the warning. Windows will now format the drive. Once complete, the drive will appear as NTFS and be ready for use.
Alternatively, you can use PowerShell. Open PowerShell as administrator and run:
Format-Volume -DriveLetter X -FileSystem NTFS -Confirm:$false
Replace
X with your drive letter. This method is faster for users comfortable with command-line interfaces.
Preventing Future RAW Issues
To avoid this situation in the future, always use the "Safely Remove Hardware" option before unplugging USB drives. Avoid disconnecting power during large file transfers. Regularly backup your important data to multiple locations. If you experience frequent RAW issues, check the health of the drive using tools like CrystalDiskInfo to monitor S.M.A.R.T. status. A drive that repeatedly fails may be nearing end-of-life and should be replaced. For more insights on handling unreadable external drives, refer to our article on

Frequently Asked Questions
Can I convert RAW to NTFS without losing data?
No, converting a RAW drive directly to NTFS requires formatting, which erases all existing data. You must recover your files first using data recovery software before performing any format operation. Attempting to bypass this step will result in permanent data loss.
Why does my drive show as RAW instead of NTFS?
This usually happens due to file system corruption, improper ejection, virus infection, or bad sectors. The operating system loses the ability to read the file table, so it defaults to showing the partition as RAW. Physical damage can also cause this symptom if the magnetic platters are degraded.
Is it safe to use CHKDSK on a RAW drive?
It is generally safe if you have already backed up your data, but it may not work on severely corrupted volumes. If
chkdsk fails to recognize the file system, it will not repair it. Always prioritize data recovery over repair attempts to minimize risk.
What should I do if data recovery software cannot find my files?
Try scanning with multiple different recovery tools, as their algorithms vary. Ensure you are performing a deep scan rather than a quick scan. If no software can recover the data, the drive may have physical damage requiring professional lab services.
How long does it take to format a RAW drive to NTFS?
A quick format typically takes a few minutes, while a full format can take several hours depending on the drive capacity and speed. The time required depends on whether you check the "Perform a quick format" option in the formatting dialog.
