Disk Drill takes much of the guesswork out of recovering a broken software RAID. Automatic reconstruction works well for supported layouts, though complex controller-based arrays may still need a specialist.
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.
Disk Drill is a Windows plus macOS recovery app that can automatically reconstruct many software RAID arrays. It scans the resulting virtual volume for deleted, formatted, corrupted, or inaccessible files.

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.
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’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.
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.
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.
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.
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 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.
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.
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.
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.
