Hetman RAID Recovery 3.2 Free Download – Complete RAID Data Recovery Guide
Hetman RAID Recovery 3.2 is a specialized data recovery application designed to help users restore information from damaged, inaccessible, or accidentally modified RAID arrays. It can analyze RAID member disks, reconstruct supported array configurations, scan storage volumes, and identify files that may still be recoverable.
RAID systems are commonly used in network-attached storage (NAS), servers, workstations, and business storage environments. Although RAID can improve performance or provide redundancy, it does not eliminate the risk of data loss. Disk failures, controller problems, accidental formatting, corrupted RAID metadata, and unsuccessful rebuild operations can make stored information inaccessible.
Hetman RAID Recovery provides a way to examine these situations without necessarily relying on the original RAID controller or NAS enclosure. Its free trial lets users reconstruct supported arrays, scan storage, and preview recoverable files before purchasing a license. Saving recovered files requires an appropriate paid license.

What Is Hetman RAID Recovery?
Hetman RAID Recovery is a data recovery tool developed by Hetman Software for working with RAID arrays and other multi-disk storage systems. It is designed to reconstruct supported storage layouts and recover accessible files after logical data loss or certain disk failures.
The application analyzes information stored on RAID member disks to determine how the original array was organized. Depending on the configuration and available metadata, it may identify disk order, stripe size, offsets, parity layout, and other parameters needed to reconstruct the storage virtually.
If automatic detection cannot determine the complete configuration, the integrated RAID Constructor can help users specify the parameters manually.
The software can be useful in situations involving:
- An inaccessible RAID volume.
- A failed or unavailable RAID controller.
- Accidental formatting or partition deletion.
- Corrupted RAID metadata.
- Certain missing or failed member disks.
- NAS or server storage that no longer mounts correctly.
- Files deleted from a supported RAID volume.
Successful recovery depends on the RAID level, the number and condition of available disks, the accuracy of the reconstructed configuration, and whether the original data has been overwritten.
Key Features of Hetman RAID Recovery
1. Automatic RAID Configuration Detection
Reconstructing a RAID array requires understanding how its member disks store data. Hetman RAID Recovery analyzes available metadata to identify supported configurations and assemble a virtual representation of the array.
The software may detect parameters such as disk order, stripe size, data offsets, and parity arrangement. When the available information is sufficient, automatic reconstruction can reduce the need for manual configuration.
Automatic detection is not guaranteed to succeed in every case. If metadata is damaged or missing, users may need to enter known parameters manually.
2. Virtual RAID Reconstruction
The application can reconstruct supported RAID arrays virtually for analysis and recovery. This is especially useful when the original controller, motherboard, server, or NAS enclosure is no longer available.
Rather than requiring users to immediately rebuild the original array, the software creates a reconstructed representation that can be examined for partitions and files.
Important: Virtual reconstruction is not the same as repairing or rebuilding the original RAID system. Avoid writing changes to the source disks while recovering data.
3. Support for Common RAID Configurations
Hetman RAID Recovery supports a range of RAID technologies and storage configurations. The exact configurations available depend on the software version and the underlying hardware or software implementation.
Common RAID levels include:
- RAID 0: Distributes data across disks for performance. Because it lacks redundancy, failure of a member disk can make the entire array inaccessible.
- RAID 1: Mirrors data across disks. Recovery may be possible from a readable mirror, depending on the failure and subsequent disk activity.
- RAID 5: Uses distributed parity and can tolerate one failed member under normal operating conditions. Recovery after additional failures depends on the remaining data and parity.
- RAID 6: Uses dual distributed parity and can tolerate two failed members under normal operating conditions, but additional damage can complicate recovery.
- RAID 10: Combines mirroring and striping. Recovery possibilities depend on which disks have failed and how the data is distributed.
Support for a RAID level does not guarantee recovery from every failed array. The number of failed disks, disk readability, and the specific configuration are important factors.
4. Recovery from Damaged RAID Arrays
RAID arrays can become inaccessible because of disk failures, controller damage, interrupted rebuilds, corrupted metadata, or accidental configuration changes.
Hetman RAID Recovery is designed to reconstruct supported arrays and search for recoverable information even when the original system cannot mount the volume.
For example, if a NAS enclosure fails but its member disks remain readable, the application may be able to reconstruct the array using those disks on another compatible computer.
If a disk is physically failing, however, repeated scanning can increase the risk of further damage. In that situation, consider creating a sector-by-sector image or contacting a professional recovery service.
5. NAS and Server Storage Recovery
Network-attached storage systems and servers often use RAID to manage several physical disks as a single logical storage volume.
When a NAS device fails, its files may remain on the member disks even though the original device is no longer accessible. Hetman RAID Recovery can help analyze supported NAS and server configurations by examining the available drives.
The software may also work with supported disk images and other storage sources. Compatibility depends on the array type, file system, device configuration, and available data.
6. File System and Partition Recovery
After reconstructing an array, the next step is to locate its partitions and examine the file system.
Hetman RAID Recovery can scan supported volumes for existing files, deleted data, and information that remains accessible after certain types of logical damage.
The application supports multiple file systems, but exact compatibility varies by version and platform. Check the developer’s documentation if your array uses a specialized file system or an encrypted volume.
7. Fast Scan and Full Analysis
The software offers different analysis options to help locate recoverable information.
Fast Scan is generally a sensible starting point when the array has been reconstructed correctly and the file system is still reasonably intact.
Full Analysis can be useful when a quick scan does not locate the required files or when the file system has suffered more extensive damage. A deeper analysis may take substantially longer, especially on large arrays.
Start with the less intensive option when appropriate, then move to a more thorough analysis if necessary. The exact options available depend on the selected storage and software version.
8. File Preview Before Recovery
Previewing files helps users assess the scan results before purchasing a license.
Hetman RAID Recovery can display supported file previews and allow users to browse detected folders. This makes it easier to identify important documents, images, and other files.
A visible file is not necessarily a fully recoverable file. Check important files carefully and verify their contents after recovery.
9. Disk Image Support
Working with disk images can reduce the need to repeatedly access unstable physical drives. Hetman RAID Recovery supports several types of disk images and storage sources, depending on the version and platform.
When a RAID member disk is unstable, creating a sector-by-sector image may preserve the readable data and provide a safer source for further analysis.
Imaging a failing drive can still be technically demanding. If the information is critical or the drive has severe hardware problems, professional assistance may be the safest approach.
Hetman RAID Recovery User Interface
Hetman RAID Recovery uses a structured interface for identifying storage devices, reconstructing RAID configurations, scanning volumes, and selecting files.
The main workflow generally involves the following areas:
- Physical disks: Lists the connected storage devices that the application can access.
- Detected RAID arrays: Displays arrays identified automatically from available metadata.
- RAID Constructor: Provides manual configuration options when automatic reconstruction is insufficient.
- Scan results: Shows the folders and files found during analysis.
- Preview window: Allows inspection of supported files before recovery.
- Recovery options: Lets users choose a destination for the restored information.
The guided workflow is useful for users who understand basic storage concepts. Manual RAID reconstruction may require more technical knowledge, particularly when disk order, stripe size, parity, or offsets are unknown.

How to Use Hetman RAID Recovery
RAID recovery requires more care than ordinary file recovery because several disks may work together to store the data. Preserve the original disks and avoid changes to the array before beginning.
Step 1: Stop Using the Affected RAID
If the array has become inaccessible or contains missing files, stop unnecessary activity immediately.
Do not initialize, format, repair, resynchronize, or rebuild the original array unless you have a verified recovery plan and suitable backups. Such operations can change metadata or overwrite information that may be needed for recovery.
If the data is business-critical, document the symptoms and seek professional help before making changes.
Step 2: Label and Connect the RAID Disks
If it is safe and appropriate to remove the member disks, label each one and record its original position and connection.
Connect all available member disks to a compatible recovery computer whenever possible. Some RAID configurations can be reconstructed with missing members, but results depend on the RAID level and the condition of the remaining disks.
For example, RAID 0 generally requires all member disks because it has no parity or mirroring redundancy. Other configurations may tolerate certain missing disks.
Avoid repeatedly reconnecting a disk that shows signs of physical failure.
Step 3: Launch the Application and Inspect Detected Arrays
Open Hetman RAID Recovery and review the available physical disks and detected arrays.
If the application recognizes the RAID configuration, check the displayed parameters and confirm that the proposed layout is consistent with the original system.
Do not assume that an automatically detected array is correct without checking whether its capacity, partitions, and file-system structure make sense.
Step 4: Use the RAID Constructor if Necessary
If automatic detection fails, the RAID Constructor may allow you to specify the array configuration manually.
Depending on the RAID type, relevant parameters can include:
- RAID level or layout.
- Member disk order.
- Stripe or block size.
- Data offsets.
- Parity arrangement.
- Controller-specific configuration.
Use the original controller documentation or previously recorded settings where possible. Guessing parameters can produce an incorrect virtual array and misleading scan results.
Step 5: Scan the Reconstructed Array
Once the array has been reconstructed, select the appropriate volume and start the available scan.
Begin with Fast Scan when the configuration appears correct and the file system is accessible. If the scan does not find the required data, consider Full Analysis or another supported deeper scan option.
Scan duration depends on the number and capacity of the disks, their read speed, the condition of the storage, and the selected analysis method.
Step 6: Review and Preview the Files
After the scan, browse the detected folders and files. Use the preview feature for supported formats to check whether the required information appears intact.
Prioritize the most important data first. If the scan displays missing folders or unexpected file names, verify that the reconstructed RAID parameters are correct before proceeding.
Step 7: Activate the Software if Needed
The free trial allows users to reconstruct the array, scan storage, and preview recoverable files. A license is required to save the recovered data.
This lets you assess whether the software has located the files you need before making a purchase.
Step 8: Recover Files to Separate Storage
Choose a destination on a different physical storage device, not on the original RAID member disks.
For example, recover the files to a separate external drive with enough free space. After recovery, open important documents and verify that they are usable.
Keep an additional backup of the restored data before attempting to repair or rebuild the original RAID.
Hetman RAID Recovery System Requirements
System requirements vary by release and operating system. Consult the official download page for current specifications before installation.
Operating System Compatibility
Hetman RAID Recovery is available for Windows, macOS, and Linux. Choose the correct package for the system you intend to use for recovery.
The system running the recovery software does not necessarily need to be the original NAS or server, provided the recovery computer can access the member disks and the software supports the array configuration.
Storage Connectivity
The recovery computer must be able to access the RAID member disks or supported disk images.
Depending on the system, you may need compatible SATA or SAS connections, adapters, a suitable controller, or other hardware to connect the drives reliably.
Memory and Storage Space
The computer needs sufficient memory and working storage for the application and recovery workflow. Recovered files also require a separate destination with enough capacity.
Large arrays and complex configurations may require more time and resources than smaller storage systems.
Permissions and Encryption
The software may require elevated permissions to access physical disks or certain storage devices.
If the RAID contains encrypted volumes, you may also need the appropriate password, recovery key, or other required credentials. RAID reconstruction alone does not bypass encryption.
Advantages of Hetman RAID Recovery
Hetman RAID Recovery offers several benefits for users dealing with RAID-related data loss.
- Dedicated RAID recovery: Designed specifically for multi-disk arrays rather than only individual drives.
- Automatic reconstruction: Can identify supported configurations from available RAID metadata.
- Manual RAID Constructor: Allows configuration parameters to be specified when automatic detection is insufficient.
- Multiple scan options: Provides different analysis methods for finding existing and lost files.
- File preview: Helps assess recovery results before purchasing a license.
- NAS and server use cases: Useful for investigating supported storage systems when the original enclosure or controller is unavailable.
- Multiple operating systems: Download packages are available for Windows, macOS, and Linux.
- Virtual reconstruction: Allows supported arrays to be analyzed without immediately rebuilding the original storage system.
These features can make the application useful for both individual users and professionals, depending on the license and complexity of the recovery task.
Limitations of Hetman RAID Recovery
Although the software can help recover data from many logical failures, it cannot guarantee that every file will be restored.
Recovery Depends on Disk Condition
Unreadable sectors, physical damage, and failed disk electronics can prevent the software from accessing essential information. Repeated scanning of an unstable disk may worsen the situation.
RAID 0 Has No Redundancy
RAID 0 distributes data across its member disks without storing parity or mirrored copies. If a member disk fails, the array may become inaccessible, and recovery can be difficult.
Incorrect Parameters Can Produce Wrong Results
RAID reconstruction depends on the correct layout. An incorrect disk order, stripe size, or parity configuration can cause the reconstructed volume to display missing or corrupted files.
Overwritten Data May Be Lost Permanently
If new data overwrites the storage blocks containing lost files, software recovery may no longer be possible.
The Trial Does Not Save Recovered Files
The free version is intended for evaluating the recovery results. A paid license is required to save recovered data, subject to the relevant edition’s restrictions.
Hetman RAID Recovery Troubleshooting Guide
RAID Array Is Not Detected
Confirm that the computer can detect the member disks. Check connections, power, adapters, and controller compatibility.
If the disks are visible but the array is not detected, review the RAID Constructor options and verify the original configuration. Avoid formatting or initializing the disks.
RAID Parameters Appear Incorrect
Compare the detected layout with the original system’s documentation, controller settings, or recorded configuration.
Verify disk order, stripe size, offsets, and parity settings where applicable. If you cannot determine the correct configuration and the data is important, seek specialist assistance rather than repeatedly experimenting on the original disks.
The Scan Does Not Find the Required Files
First confirm that the virtual RAID has been reconstructed correctly. Then try another supported analysis option, such as Full Analysis.
A deeper scan may locate additional files, but it cannot recover information that has been overwritten or is no longer readable.
The Scan Is Too Slow
Large arrays can take substantial time to analyze, especially when individual disks have read errors.
Avoid running unnecessary disk-intensive tasks during recovery. If a disk is unstable, stop repeated scanning and consider creating a sector-by-sector image or obtaining professional assistance.
Recovered Files Are Corrupted
Corrupted files may indicate overwritten data, missing disk blocks, or an incorrect RAID reconstruction.
Verify the array parameters and compare results with available backups. Some files may remain unrecoverable even when their names appear in the scan results.
The Software Requests Activation
This is expected when the trial has located data but saving the files requires a license. Review the license editions and select the one that matches the array size and intended use.
Hetman RAID Recovery vs. Other Recovery Tools
Different tools serve different purposes, so selecting the right option depends on the type of failure.
Hetman RAID Recovery
This application focuses on reconstructing supported RAID configurations and recovering files from multi-disk storage systems. It is suitable for cases involving NAS devices, server storage, and damaged or inaccessible arrays.
General File Recovery Software
General-purpose tools are often designed for individual disks, USB drives, or memory cards. They may be useful for ordinary file deletion but may not provide the RAID reconstruction features needed for a multi-disk array.
RAID Controller Utilities
Controller utilities are generally intended to configure, monitor, or rebuild arrays associated with specific hardware. They can be important for normal RAID management, but rebuilding a damaged array without a recovery plan may place remaining data at risk.
Which Tool Should You Choose?
Use a dedicated RAID recovery application when the original array cannot be accessed and the goal is to reconstruct its layout and recover files. Use controller management utilities for routine maintenance only when the array’s condition and backup status are understood.
If the disks have physical damage or the data is irreplaceable, a professional recovery service may be safer than a do-it-yourself attempt.
Is Hetman RAID Recovery Free?
Hetman RAID Recovery is free to download and test, but the trial does not provide unrestricted free file recovery.
According to the official download page, the trial allows users to reconstruct supported RAID arrays, scan storage, browse detected folders, and preview recoverable files. A license is required to save the recovered data.
The developer offers different license editions:
- Home: Intended for personal, non-commercial use and supports RAID arrays with up to three member disks.
- Office: Intended for internal business and professional IT use, with support for arrays of up to five member disks.
- Business: Intended for recovery specialists and service providers who need commercial client recovery and support for larger arrays.
License terms and availability may change. Review the official license and pricing page before purchasing.
The practical advantage of the trial is that you can evaluate the scan results first, rather than paying before confirming whether the application finds the information you need.
Safety Tips Before RAID Recovery
RAID recovery can involve several disks and complex storage metadata. Following safe practices is essential to preserve the remaining data.
- Stop using the affected array: Avoid writing new files or running unnecessary operations.
- Do not initialize or format disks: These actions can make recovery more complicated.
- Avoid rebuilding or resynchronizing the array prematurely: A rebuild can overwrite information needed for recovery.
- Label the member disks: Record their original order and connections before removing them.
- Connect all available disks when possible: Some RAID levels need all members, while others may tolerate certain missing disks.
- Create disk images where appropriate: A sector-by-sector image can help preserve readable data from unstable drives.
- Save recovered files elsewhere: Use a separate physical storage device.
- Verify the restored files: Check important documents, databases, and projects before relying on them.
- Keep backups: RAID redundancy is not a substitute for an independent backup.
If a disk is clicking, overheating, repeatedly disconnecting, or reporting serious read errors, stop and consider professional recovery services.
Who Should Use Hetman RAID Recovery?
Hetman RAID Recovery may be useful for several types of users.
- Home users: Recovering files from supported personal RAID storage.
- IT administrators: Investigating inaccessible storage volumes and server failures.
- Small businesses: Attempting to restore important data from supported business storage systems.
- NAS owners: Recovering files when a supported NAS enclosure or controller becomes unavailable.
- Data recovery specialists: Examining supported RAID configurations and recovering client data under the appropriate license.
The software is most useful when the member disks remain accessible and the RAID configuration can be reconstructed. Physical damage, severe disk failure, encryption, and overwritten data can limit the results.
Final Verdict
Hetman RAID Recovery is a specialized tool for reconstructing supported RAID arrays and recovering files from inaccessible or damaged multi-disk storage. Its automatic detection, manual RAID Constructor, scan options, and file-preview features help users evaluate whether their lost information can be recovered.
The free trial is useful for checking the array and previewing recoverable files before purchasing a license. However, saving recovered data requires a paid license, and recovery success depends on the RAID configuration, the condition of the member disks, and the state of the lost information.
For the safest approach, download the software from the official developer website, preserve the original disks, avoid rebuilding or formatting the array prematurely, and save recovered files to separate storage.
