Best NAS Data Recovery Software for 2026
NAS recovery is rarely a one-click job. We compared five tools for readable arrays, lost shares, damaged members, plus less common RAID layouts.
Disk Drill is the best overall NAS recovery choice for most home or small-office cases because its scanning, previews, filtering, plus disk-image workflow are easier to manage. Pick UFS Explorer instead if you need to rebuild Synology Hybrid RAID, Drobo BeyondRAID, Btrfs RAID, or a custom layout.

9.0/10
UFS Explorer RAID Recovery
Windows, macOS, plus Linux · SysDev Laboratories
UFS Explorer RAID Recovery is the stronger pick once a NAS layout stops being ordinary. It supports Synology Hybrid RAID, Drobo BeyondRAID, Btrfs RAID, nested RAID levels, Linux mdadm, LVM, ZFS, plus manual configurations. It can read RAID metadata automatically, yet still lets an experienced operator define a layout by hand. (sysdevlabs.com)
Its imaging controls are another reason to shortlist it for weak disks. Read timeout, block size, direction, defective-block maps, plus adaptive reconstruction are available. The personal license costs €129.95 for one operating system. Trial recovery is restricted to files smaller than 768 KB. (sysdevlabs.com)
Best forExperienced users rebuilding Synology, QNAP, Drobo, Buffalo, Btrfs, or custom RAID layouts
- Excellent support for NAS-specific storage layouts
- Handles SHR, BeyondRAID, Btrfs RAID, ZFS, plus nested arrays
- Detailed disk-imaging controls for unstable media
- Automatic metadata reading plus a manual RAID builder
- Available for Windows, macOS, plus Linux

- Trial only copies files below 768 KB
03 R-Studio
Windows, macOS, plus Linux · R-Tools Technology
8.7/10
R-Studio
Windows, macOS, plus Linux · R-Tools Technology
R-Studio provides a wide toolset for $79.99, including automatic RAID parameter detection, common RAID levels, reverse arrays, Linux mdadm, LVM, Storage Spaces, Apple software RAID, plus recovery over a network. It also reads Ext, XFS, APFS, HFS, UFS, NTFS, ReFS, plus several virtual-disk formats. (r-studio.com)
The interface exposes many choices early, so a first-time user can select the wrong object or scan mode. For an IT admin who understands member order, stripe size, parity rotation, plus offsets, that density becomes useful rather than annoying. The standard license is permanent, though each host operating system needs its own registration key. (r-studio.com)

04 ReclaiMe File Recovery
Windows · ReclaiMe
8.3/10
ReclaiMe File Recovery
Windows · ReclaiMe
ReclaiMe takes an unusual route for simpler NAS incidents. If the appliance still runs, the Ultimate edition can connect over the network, which may avoid removing disks for an accidental-deletion case. Its official NAS guidance prices the Ultimate license at $199.95. (reclaime.com)
That convenience does not replace a physical member-disk workflow when a drive has failed, the array will not mount, or the NAS presents the wrong capacity. Those cases usually require powering down the enclosure, labeling each member, then connecting or imaging the disks individually. ReclaiMe is also limited to Windows.
Best forWindows users recovering deleted NAS files while the appliance still works plus remains reachable over the network
- Can recover through the network in suitable logical-loss cases
- Straightforward scan-first workflow
- Good fit for a NAS that still boots plus exposes storage
- Preview can confirm useful files before purchase
- Windows only
- Ultimate costs more than several rivals
- Failed arrays still require direct access to member disks
05 DMDE
Windows, macOS, Linux, plus DOS · DMDE Software
8.0/10
DMDE
Windows, macOS, Linux, plus DOS · DMDE Software
DMDE offers uncommon depth at a modest price. Its virtual RAID constructor supports RAID 0, 1, 4, 5, 6, delayed parity, custom striping, JBOD, plus automatic parameter calculation. Disk cloning includes I/O error handling plus reverse copying, which is valuable when a member disk reads poorly. (dmde.com)
The free edition can recover up to 4,000 files from the active panel per request. Express costs $20 for one year, while Standard is a $48 perpetual license. Low pricing does not make it beginner-friendly. A wrong disk order, stripe pattern, or parity setting can produce believable folders filled with broken files. (dmde.com)
Best forPatient technical users who know RAID parameters or are willing to verify several reconstructed layouts
- Far cheaper than most RAID-capable alternatives
- Free edition permits limited file recovery
- RAID constructor plus automatic parameter calculation
- Portable builds for several operating systems
- Disk cloning includes controls for read errors
- Steep learning curve
- Layout mistakes can produce misleading results
- Express license lasts one year plus covers one OS family
How We Evaluated NAS Data Recovery Software
We compared each tool against the jobs that cause trouble in real NAS recoveries: recognizing member disks, assembling virtual RAID, reading Linux file systems, creating disk images, handling bad sectors, previewing intact files, plus saving scan sessions. The reference workflow used four-member RAID 5 image sets, a mirrored Ext4 set, a deleted shared folder, plus a deliberately incomplete array.
Scores favor safe imaging, understandable previews, useful RAID controls, transparent trial limits, plus pricing a home or small-business user can verify before paying. Recovery percentages were not used because a single number would hide major differences in disk health, overwrite activity, encryption, plus array geometry.
How to Choose NAS Data Recovery Software for Your Array
Start with the failure type, not the NAS logo. A deleted folder on a healthy, mounted share may only need a network-capable scan. A failed RAID, missing storage pool, or dead enclosure usually requires access to each member disk plus software that can reconstruct the original layout.
Check the file system too. Synology, QNAP, Asustor, Drobo, plus home-built servers may use Ext4, Btrfs, ZFS, XFS, mdadm, SHR, BeyondRAID, LVM, or another layer. The best tool is the one that understands every layer in your exact stack while letting you preview several large files before purchase.
Common NAS Data Recovery Mistakes to Avoid
Do not initialize disks, rebuild the pool, replace several members at once, update firmware, or accept a prompt to repair the file system. Those actions change metadata that recovery software may need. Label each disk by bay number before removal, then photograph the original arrangement.
Never restore files to the source array. Save recovered data to separate storage with enough free space for the full result. If any disk clicks, stalls, overheats, or disappears during reads, stop. Repeated full scans are not a harmless experiment on failing hardware.
Which NAS Recovery Tool Should You Use?
Disk Drill wins for its approachable scan, preview, filtering, plus imaging workflow. It is the sensible first trial for a readable Linux RAID, deleted share, reformatted volume, or disk image.
UFS Explorer is a better match for unusual vendor RAID or missing-member reconstruction. R-Studio offers broad technical value, ReclaiMe helps with reachable network storage, while DMDE is hard to beat on price if you already understand RAID geometry.
Create images of every readable member disk first, preserve the original disk order, then test the top two tools against those images rather than rescanning the physical drives.
