A Strong Pick for Software RAID Recovery Easy reconstruction, useful previews, broad layout support
Recommended
Quick verdict

Disk Drill is a practical first choice for failed software RAID, Storage Spaces, Linux RAID, plus Synology SHR. It detects supported arrays automatically, builds a virtual volume, then lets you scan or preview files before paying. Hardware damage plus unusual controller metadata remain jobs for a recovery lab.

How We Evaluated Disk Drill for RAID Data Recovery

We focused on the parts of Disk Drill that matter during a failed-array recovery: member detection, virtual reconstruction, file-system recognition, result filtering, previews, imaging, licensing, plus recovery safeguards. Supported layouts were checked against CleverFiles’ current RAID documentation, including Linux RAID, Windows RAID, Storage Spaces, BTRFS, JBOD, plus Synology SHR.

Scores favor a clear route from connected members to usable previews. We lowered the reconstruction score for the lack of a full manual builder, then marked safety down because no desktop app can deal responsibly with severe mechanical failure.

When Disk Drill Is the Wrong Choice for a Failed RAID

Do not run a long scan if one or more disks click, spin down, disappear repeatedly, or report rapidly rising bad-sector counts. Continued reads can turn a partly recoverable disk into a dead one. A professional lab is safer when the missing files are irreplaceable.

Disk Drill is also a poor fit if the array uses proprietary enterprise-controller metadata, encryption keys you do not have, or a nested layout the app cannot identify. In that case, a configurable RAID editor or a specialist may be needed.

Disk Drill RAID Recovery Features in Detail

01

RAID Reconstruction

Automatic detection removes a lot of manual setup

9.3/10

Disk Drill’s strongest RAID feature is its ability to recognize supported member disks, assemble them virtually, then present the result as one volume. That avoids the stripe-size guessing plus disk-order trial runs common in more technical recovery utilities.

Coverage includes common Linux RAID layouts, Windows software RAID, Storage Spaces, BTRFS arrays, JBOD, plus Synology SHR-1 or SHR-2. All available members should be connected at once. Disk Drill labels a reconstructed array as valid, recovered, or corrupted, which gives useful context before a long scan begins.

The limit matters. Reconstruction is automatic rather than fully configurable. Proprietary controller metadata, unusual offsets, nested arrays, or badly damaged members may exceed what the app can assemble.

The upside
  • Automatic discovery of supported RAID members
  • Virtual reconstruction leaves the source layout untouched
  • Support for Linux RAID, Storage Spaces, JBOD, plus Synology SHR
  • Clear array-condition labels before scanning
The catch
  • No full manual RAID builder for unusual geometry
  • Professional hardware-controller arrays have limited support

Recovery Workflow

A guided process that stays readable on large arrays

9.1/10

Once Disk Drill assembles the virtual array, recovery feels similar to scanning a normal drive. Results can be narrowed by file type, size, date, name, or recovery chance. That matters on a multi-terabyte NAS where an unfiltered result list can become nearly useless.

Previewing is the key step. Documents, photos, video clips, plus other supported files can be checked before recovery. A complete, error-free preview is a much better reason to purchase than a simple file count. Scan sessions can also be saved, which prevents needless rescanning after a pause.

The upside
  • Clean device list with a separate RAID section
  • Search plus filters help with very large result sets
  • File previews available before purchase
  • Scan sessions can be reviewed later
The catch
  • Deep scans of large arrays can take many hours
  • Recovered folders may be less tidy after signature-based scanning

File System Coverage

Useful across mixed NAS, Windows, plus Mac storage

8.9/10

Disk Drill recognizes the file systems commonly found inside home NAS boxes, workstations, plus small servers. Supported RAID recovery can cover NTFS, FAT32, exFAT, ReFS, HFS+, APFS, EXT2, EXT3, EXT4, plus BTRFS.

This breadth is handy after moving member disks to a different computer. A Linux NAS array can be connected to a Windows or Mac recovery station without requiring the original NAS interface. If the file system cannot be rebuilt, Disk Drill can still search by file signature, though original names plus folder structure may be lost.

The upside
  • Covers major Windows, Mac, plus Linux file systems
  • Recognizes BTRFS used by many modern storage systems
  • Signature scans can find files after metadata loss
  • Works with directly connected NAS member disks
The catch
  • RAW recovery may lose original filenames
  • Some proprietary NAS formats need another tool

Recovery Safety

Disk imaging helps reduce stress on questionable drives

8.8/10

A failing RAID member should not be pushed through repeated deep scans. Disk Drill includes byte-to-byte imaging, letting you copy a readable disk into an image before searching for files. The image can then replace the original member during safer recovery work.

The software reconstructs arrays virtually rather than writing a rebuild onto the source disks. Recovered data must still go to separate storage. Disk Drill cannot make a mechanically failing drive safe, so clicking, disappearing, or non-spinning disks should be powered down.

The upside
  • Byte-to-byte images can preserve readable sectors
  • Virtual assembly avoids rebuilding onto source members
  • Preview helps identify damaged files before export
  • Disk health details can flag some drive problems
The catch
  • Imaging requires substantial spare capacity
  • Software cannot fix physical disk failure

Cost and Licensing

A free evaluation followed by two paid choices

8.4/10

Disk Drill Basic lets you assemble supported arrays, scan them, plus preview recoverable files before buying. Windows users can recover up to 100 MB free. The Mac edition mainly uses its free tier for scanning, previews, plus recovery of previously protected data.

Disk Drill PRO costs $89 per year or $149 for a lifetime license. One personal license covers Windows plus macOS for one user on as many as three devices. The annual option renews automatically unless canceled. Purchases are generally final, so preview several important files before paying.

The upside
  • Unlimited scanning plus previews in Basic
  • One license covers Windows plus macOS
  • Lifetime plan includes future upgrades
  • Up to three device activations
The catch
  • 100 MB is too little for meaningful RAID recovery
  • Annual plan renews automatically
  • Refund policy is restrictive
Basic $0 Scan plus preview free · Windows recovery limited to 100 MB
PRO Annual $89/yr Unlimited personal recovery · Auto-renewing
PRO Lifetime $149 One-time payment · Future upgrades included

What Disk Drill Users Report After Real Recoveries

The poster recovered photos plus fragmented camera videos from a RAW SD card after other utilities failed to recognize it. They liked the previews, simple workflow, plus Advanced Camera Recovery, though the test did not involve RAID.
Reddit user · r/DataRecoveryHelp
One commenter said the scan suggested files were recoverable, yet the paid recovery did not produce usable results. Their complaint focused heavily on the purchase plus refund experience.
Reddit user · r/DataRecoveryHelp
A user comparing several tools reported that Disk Drill failed to restore an intact NTFS folder tree from one damaged drive, while DMDE found the structure quickly. It is a useful reminder to compare scan results before committing.

Should You Use Disk Drill for RAID Recovery?

Disk Drill is easy to recommend for supported software RAID arrays whose member disks remain readable. Automatic assembly, strong file-system coverage, previews, plus disk imaging make a stressful recovery job much easier to manage. Skip it if drives click, vanish from the operating system, or belong to an obscure enterprise controller with unusual metadata.

The free scan is genuinely useful. Let it reconstruct the array, preview several critical files from different folders, then choose a license only if those previews look complete.

Label every member disk, image any unstable drive first, then recover files to storage that is completely separate from the original array.

Disk Drill RAID Recovery Questions, Answered

Can Disk Drill recover data from a failed RAID array?
Yes, if the array type is supported plus enough member disks remain readable. Disk Drill reconstructs the array virtually, then scans that virtual volume for files.
Which Linux RAID levels does Disk Drill support?
Documented Linux RAID coverage includes RAID 0, RAID 1, RAID 5, RAID 6, RAID 10 or 1E, plus JBOD. BTRFS layouts also receive dedicated support.
Does Disk Drill recover Windows Storage Spaces?
Yes. It supports Simple, two-way mirror, three-way mirror, parity, plus dual-parity Storage Spaces layouts.
Can Disk Drill recover a Synology RAID?
Disk Drill supports SHR-1 plus SHR-2, along with several standard Linux RAID layouts used by NAS hardware. The member disks normally need direct connections to the recovery computer.
Does Disk Drill work with QNAP NAS drives?
Many QNAP systems use standard Linux RAID layouts that Disk Drill can recognize. Compatibility still depends on the RAID geometry, file system, encryption, plus member condition.
Must every RAID disk be connected at the same time?
Connect all available members simultaneously whenever possible. Missing disks reduce reconstruction accuracy, particularly with striped or parity-based layouts.
Can Disk Drill rebuild RAID manually?
Not fully. Its current reconstruction workflow is automatic, so it is less suitable when disk order, stripe size, offsets, or parity rotation must be entered by hand.
Will Disk Drill alter the original RAID disks?
The app assembles supported arrays virtually rather than rebuilding data onto the source members. Still, save recovered files elsewhere plus avoid any operating-system prompt to initialize or format a disk.
Should I image RAID disks before scanning?
Image a member first if it is unstable, unusually slow, or showing read errors. Healthy disks can often be scanned directly, though images provide a safer working copy.
How much free RAID data can Disk Drill recover?
Disk Drill Basic permits free scanning plus previews. Windows recovery is limited to 100 MB, which is mainly useful for testing rather than a full RAID restore.
How much does Disk Drill PRO cost?
As of August 2026, Disk Drill PRO is $89 per year or $149 for a lifetime license. The personal license covers Windows plus macOS for one user on up to three devices.
Can I preview RAID files before purchasing Disk Drill?
Yes. Scan plus preview several important files in the free Basic edition. Check files from different folders rather than relying on one successful image preview.
Can Disk Drill recover the original RAID folder structure?
It may restore names plus folders when usable file-system metadata survives. A signature-based scan can recover content after severe metadata loss, though results may have generic names or type-based folders.
Does Disk Drill support encrypted RAID arrays?
Recovery depends on whether the array can be unlocked with valid credentials or keys. Disk Drill cannot bypass unknown encryption.
Can Disk Drill recover RAID data after a controller failure?
Possibly, especially if the controller used a standard software-compatible layout. Proprietary controller metadata may prevent automatic reconstruction.
What if a RAID member makes clicking sounds?
Power it down. Clicking usually points to physical trouble, where repeated scans can cause more damage. Contact a recovery lab if the data matters.
Can recovered files be saved back to the RAID?
Do not save them to any original member or to the reconstructed array. Use a separate healthy disk with enough free space for the entire recovery.
Is Disk Drill a replacement for RAID backups?
No. RAID reduces downtime from certain disk failures, while a backup protects against deletion, corruption, ransomware, theft, plus catastrophic array loss.
