EaseUS Data Recovery Wizard Pro vs Wondershare Recoverit Ultimate: Recovering Lost RAW Partition Data on Windows 11 NVMe SSDs

As a Senior Technical Support Engineer and PC Security Specialist, I frequently encounter critical data loss scenarios. One of the most challenging, yet often recoverable, situations is when a partition on a high-performance NVMe Solid State Drive (SSD) suddenly appears as "RAW" in Windows 11. This guide provides a comprehensive, actionable approach to recovering your invaluable data, pitting two industry-leading tools – EaseUS Data Recovery Wizard Pro and Wondershare Recoverit Ultimate – against this formidable challenge.

Symptom Analysis & Why This Error/Issue Occurs

Symptoms of a RAW Partition on an NVMe SSD

When an NVMe SSD partition becomes RAW, Windows 11 can no longer recognize its file system (e.g., NTFS, FAT32, exFAT). Key indicators include:

Disk Management Display: The partition shows up with "RAW" under the File System column, or no file system is listed at all.
Error Messages: Attempting to access the drive may result in prompts like "You need to format the disk in drive X: before you can use it," "The volume does not contain a recognized file system," or "Data error (cyclic redundancy check)."
Inaccessibility: Files and folders on the affected partition become entirely inaccessible.
Slow Performance: In some cases, the system might experience sluggishness or freezes when attempting to interact with the problematic drive.

Common Causes of RAW Partitions on NVMe SSDs

Several factors can lead to an NVMe SSD partition becoming RAW:

Corrupted File System: This is the most frequent cause, often due to sudden power outages, improper system shutdowns, or system crashes.
Damaged Partition Table/MFT: The Master File Table (MFT) for NTFS or the partition table itself (GPT/MBR) can become corrupted, making the partition unreadable.
Bad Sectors: While less common on SSDs than HDDs, logical bad blocks or controller issues can render parts of the drive, including file system metadata, inaccessible.
Driver Issues: Outdated or corrupted NVMe drivers can sometimes interfere with how Windows interacts with the SSD.
Malware/Virus Attacks: Malicious software can damage the file system or partition structures.
Unsafe Ejection/Migration Errors: Abruptly disconnecting an external NVMe enclosure or errors during OS migration can lead to corruption.
Firmware Bugs: Rare but possible, SSD firmware issues can cause data integrity problems.

Pre-requisites & Safety Backups

Essential Pre-recovery Checklist

Before attempting any recovery, observe these crucial steps to maximize your chances of success and prevent further data loss:

Stop Using the Drive Immediately: Any write operations to the RAW partition can overwrite lost data, making recovery impossible.
Do NOT Format the Drive: Windows will prompt you to format. Formatting will create a new file system and severely reduce recovery chances.
Prepare a Separate Storage Device: You will need another drive (internal/external HDD, SSD, or network share) with sufficient space to save the recovered data. Never recover data to the same drive you are scanning.
Ensure Stable Power: A power disruption during recovery can cause further data loss. Use a UPS if possible.
Administrator Privileges: You will need an administrator account to run command prompt commands or install recovery software.

The Importance of Drive Cloning (Forensic Best Practice)

For critical data, the absolute safest first step is to create a byte-for-byte clone or disk image of the affected NVMe SSD. This allows you to perform recovery attempts on the cloned image, leaving the original drive untouched. If a recovery attempt fails or causes further damage, you still have the original state to fall back on. Tools like Macrium Reflect Free, Acronis True Image, or Clonezilla can accomplish this.

Warning: Attempting recovery directly on a failing or severely corrupted drive increases the risk of complete data loss or hardware failure. Always prioritize creating a backup image if the data is irreplaceable.

Step-by-Step Actionable Solutions

Solution 1: Initial Checks with Diskpart & Chkdsk (Limited Success for RAW)

Sometimes, a RAW partition is merely a logical error that chkdsk or diskpart can resolve, especially if the file system metadata is only lightly corrupted. However, use chkdsk with caution on RAW partitions, as it can sometimes exacerbate data loss by attempting to "fix" something it doesn't fully understand, potentially overwriting recoverable data structures. This method is primarily for diagnosing or minor fixes.


1.  Open Command Prompt as Administrator:
    Press Win + X, then select "Terminal (Admin)" or "Windows PowerShell (Admin)".

2.  Launch Diskpart:
    Type diskpart and press Enter.

3.  List Disks and Volumes:
    In the DISKPART prompt, type list disk and press Enter to identify your NVMe SSD.
    Then type select disk X (replace X with your NVMe disk number) and press Enter.
    Finally, type list volume and press Enter to find the RAW partition (it will likely show "RAW" or no file system). Note its drive letter (e.g., F).

4.  Exit Diskpart:
    Type exit and press Enter.

5.  Attempt Chkdsk (Use with caution!):
    Back in the Administrator Command Prompt, type:
    chkdsk F: /f (Replace F: with the actual drive letter of your RAW partition)
    

    If chkdsk reports "The type of the file system is RAW. CHKDSK is not available for RAW drives," it means the file system is too corrupted for chkdsk to recognize or repair. In this case, you MUST proceed with dedicated data recovery software. Do NOT try chkdsk F: /r or similar commands as they are for recognized file systems.
