CHKDSK Is Not Available for RAW Drives (3 Proven Fixes)

PAGE CONTENT:

When you're trying to run CHKDSK to fix a hard drive issue, encountering the error message "CHKDSK is not available for RAW drives" can be frustrating. This message usually pops up when your drive has switched to a RAW file system, meaning it's no longer accessible or recognized by your operating system as a readable file format. A RAW drive prevents access to data stored on it, making it essential to understand why this happens and, more importantly, how to fix it.

In this detailed guide, we will explain what the RAW file system is, why CHKDSK doesn't work for RAW drives, and how you can recover your data and resolve this issue effectively.

Introduction of CHKDSK is not available for RAW drives

The error message "CHKDSK is not available for RAW drives" indicates that your drive's file system is damaged or missing. CHKDSK, the standard Windows command-line tool for scanning and repairing disk issues, only works with recognized file systems like NTFS, FAT32, or exFAT. When the file system switches to RAW, CHKDSK can't function, as it requires an existing, readable file system.

Causes of a RAW Drive:

Understanding why a drive turns RAW can help prevent similar issues in the future. Several factors can cause a drive to switch to a RAW state:

• File System Corruption: When critical data structures that define the file system become corrupted, the system can no longer recognize the file system as valid, leaving the drive in a RAW state.
• Sudden Power Failures: Abrupt power interruptions while the drive is in use, such as during file transfers, can damage the file system, causing the drive to become RAW.
• Virus or Malware Attacks: Certain types of malware can target storage devices, corrupting the file system or other drive components, making the drive inaccessible.
• Improper Drive Removal: Removing a drive (external hard drive, USB, SD card) without safely ejecting it can lead to corruption, turning the file system into RAW.
• Physical Damage: External or internal hard drives can sustain physical damage due to drops, shocks, or faulty hardware components, causing the file system to malfunction.

Consequences of a RAW Drive:

When a drive becomes RAW, it leads to several serious issues:

• Inaccessibility of Data: Files stored on a RAW drive are not accessible. Any attempts to open, view, or transfer data from the drive will result in errors.
• Potential Data Loss: If you don't resolve the RAW issue promptly, you may lose all the data stored on the drive. Especially when formatting is involved, all data can be wiped out if not recovered beforehand.
• Further Damage Risk: Continuing to use a RAW drive without addressing the problem could lead to more severe issues, such as bad sectors or permanent damage, reducing the chances of recovery.

How to Fix a RAW Drive without Losing Data?

Before attempting any fix, it's important to note that fixing a RAW drive might result in data loss. Therefore, recovering data from the drive before proceeding with any formatting or repair efforts is strongly recommended.

Step 1. Recover Lost Data from the RAW Drive

Data recovery software - such as Donemax Data Recovery can help you deeply scan the RAW drive and recover all existing/lost data.

1. Download and install Donemax Data Recovery on your computer, launch it after installing.

2. Open Donemax Data Recovery, select the RAW drive to start data recovery.

3. Click on Scan button to deeply scan the RAW drive and find all recoverable files.

4. Once the scan is completed, you can preview all recoverable files. Then select the wanted files, click on Recover button.

Step 2. 3 Methods to Fix RAW Drive

Method 1: Convert RAW to NTFS Using Command Prompt (CMD)

The most straightforward way to fix a RAW drive is by converting it back to a usable file system such as NTFS using Command Prompt. Here's how to do it:

1. Open Command Prompt as Administrator: Press Win + X and select Command Prompt (Admin) from the menu.

2. Use Diskpart to Select the RAW Drive: In the Command Prompt window, type the following and press Enter: diskpart
Type the command below to list all available drives and press Enter: list disk
Identify the RAW drive from the list and select it by typing: select disk X
Replace X with the drive number of the RAW drive.

3. Format the Drive: After selecting the correct drive, type the following command to format it to NTFS: format fs=ntfs quick

This command will quickly format the drive to NTFS, allowing you to reuse the drive.

Method 2: Use Third-Party Disk Repair Software

If you're not comfortable using Command Prompt or need a more user-friendly solution, you can use third-party disk repair software. Some popular tools that help fix RAW drives include:

• Donemax Data Recovery: This tool allows you to convert RAW drives to NTFS without losing data.
• MiniTool Partition Wizard: This tool offers a straightforward way to fix RAW drives and recover data.
• AOMEI Partition Assistant: Another powerful utility for converting RAW to NTFS and fixing file system errors.

Third-party tools provide step-by-step instructions and a graphical interface, making the process simpler. However, be sure to choose reliable software to avoid data corruption or security issues.

Method 3: Format the RAW Drive (as a Last Resort)

If the methods above don't work, formatting the drive is often the final option. Formatting will erase all data, so ensure you've recovered everything important first.

1. Open Disk Management (Win + X > Disk Management).
2. Find the RAW drive in the list of disks.
3. Right-click the RAW drive and select Format.

4. Choose NTFS or FAT32 as the file system.

5. Follow the on-screen prompts to complete the formatting process.

Once the format is complete, the drive will be usable again, but all previous data will be lost unless it was recovered beforehand.
