- 01
Correct reconstruction
RAID array reconstruction with correct parameters
We have reconstructed RAID 0, 1, 5, 6, 10, 50, and 60 by identifying stripe size, parity order, disk order, offset, and rotation, then rebuilding a virtual RAID group for safe extraction.
- Stripe size, parity order, disk order, offset, and rotation are checked before extraction.
- Hardware controllers, software arrays, and proprietary systems including ZFS RAIDZ and Drobo BeyondRAID are all in scope.
- Nested, parity based, and complex arrays are rebuilt virtually instead of on the original media.
- 02
Protected handling
Work from images, not live disks
We clone member disks at sector level, verify read errors, and keep originals write protected to preserve the condition of the original state and prevent overwrite or any further complications.
- Member disks are cloned at sector level before recovery work begins.
- Read errors are verified against the cloned images, not guessed from the live array.
- Originals stay write protected across unstable HDD, SSD, SAS, SATA, and NVMe media.

Coverage depth
Filesystem, encrypted, and virtual workload support
We repair damaged filesystems and metadata, handle encrypted volumes when keys are available, and recover virtual workloads when storage metadata is damaged.
- We repair NTFS, ReFS, ext4, XFS, Btrfs, ZFS, HFS plus, APFS, and VMFS issues by parsing MFT, inodes, journals, superblocks, and allocation bitmaps.
- We can recover data from BitLocker, LUKS, and VeraCrypt volumes when keys are available.
- Damaged VM disk containers and SAN LUNs are handled when metadata is damaged.

When RAID Recovery Requires Professional or Lab-Based Intervention
RAID data recovery is the work of an expert team that can diagnose failures across disks, controllers, firmware, and filesystems without causing extra damage. R3 Data Recovery is a trusted, professional, top-rated provider with a disciplined approach to rebuild, resynchronise, and extract data from unstable arrays.
Our engineers diagnose degraded and failed RAID arrays using logs, SMART data, controller event logs, and a sector level scan. We then image each member disk with controlled read retries to manage bad sectors, CRC errors, and uncorrectable errors. You get a recovery plan based on evidence, not guesswork.
We handle hardware RAID and software RAID, including mdadm, LVM stacks, Storage Spaces, and mixed RAID controller migrations. We also correct common human error cases like wrong drive order, accidental reinitialise, failed rebuild, or a replacement disk added to the wrong slot.
You get clear outcomes: what's recoverable, what's corrupted, what's missing, and what we can retrieve first. We verify results with file and folder validation, hash checks when requested, and structured restores to new storage. You'll deal with one team end to end, from triage to final export.

RAID Symptoms That Mean You Should Stop Using DIY Recovery Tools
RAID data recovery is needed when your array turns inaccessible, starts returning I/O errors, or shows rebuild and resilver activity that never completes.
When to stop
Repeated read errors, failed rebuilds, clicking drives, and volumes flipping online and offline are escalation signals. Continued use can overwrite parity and metadata.
- Stop rebuilds
- Preserve disk order
- Avoid repair tools
- Signal 1Failed rebuild
Array shows degraded, then fails during rebuild
A RAID 5 or RAID 6 rebuild can hit a second read error, leaving the volume offline. You may see pending sectors, reallocated sectors, or SMART warnings across member disks.
Stop the rebuild and keep the member disks in order.
- Signal 2Controller fault
Controller or HBA failure after a power event
A surge or brownout can corrupt NVRAM, cache metadata, or RAID parameters. You may see a foreign configuration prompt, missing LUNs, or a virtual disk that mounts read only.
Preserve the controller configuration before changing hardware.
- Signal 3Drive order risk
Wrong disk order or wrong slot mapping
A chassis move, backplane issue, or hot swap can scramble drive order. The RAID set may appear unformatted, show RAW, or mount with an invalid partition table on GPT or MBR.
Label every drive and bay before removing anything.
- Signal 4Logical damage
Filesystem corruption and journal replay loops
NTFS MFT damage, ext4 journal faults, XFS log issues, or ZFS checksum errors can make volumes mount and unmount repeatedly.
Avoid repair tools until the array has been imaged.
- Signal 5Metadata overwrite
Accidental initialise, reconfigure, or Storage Spaces changes
A reinitialise or reconfigure on a hardware RAID controller can wipe metadata references while leaving blocks intact. Storage Spaces and Dynamic Disks can also lose mapping tables.
Do not initialise, import, or rebuild the array again.

How RAID Data Recovery Works: From Diagnosis to Final Verification
A controlled lab workflow protects original media, reconstructs the RAID set, and restores data to safe storage without trial-and-error rebuilds.
Original media
Write protected before analysis
Array model
Parameters rebuilt virtually
Recovered data
Verified before restore
- Step 1Failure context
Triage and intake
We record symptoms, RAID level, enclosure model, controller type, and recent events like rebuild, scrub, power loss, or firmware update.
- Step 2Array geometry
Diagnostics and parameter discovery
We inspect member disks, check SMART logs, scan for metadata, and analyse parity rotation, stripe size, block alignment, and disk order.
- Step 3Protected copies
Imaging and cloning
We create sector level images with a write blocker where required, then map bad blocks and manage timeouts on unstable HDD, SSD, SATA, SAS, or NVMe media.
- Step 4Controlled rebuild
Virtual rebuild and verification
We rebuild or reconstruct the RAID group in a controlled environment, validate parity, verify consistency, and mount filesystems for logical checks.
- Step 5Verified output
Extraction and restore
We extract files and folders, carve data when metadata is missing, then export to your supplied target storage with directory structure preserved where possible.
RAID Brands, Controllers, Levels, and Configurations We Can Recover
RAID data recovery is safer when you use proven storage platforms, reliable adapters, and controlled imaging tools. R3 Data Recovery works with arrays and devices from leading vendors, then protects your data by imaging first and keeping originals unchanged.
- Dell EMC
- HPE
- IBM
- Lenovo
- Synology
- QNAP
- NetApp
- LSI Broadcom
- Adaptec
- Areca
We keep recovery work isolated from production networks, use clean connection paths through tested docks and HBAs, and verify restores before return media leaves our lab.

Pegasus RAID box, 10 years of photos
“When I thought I had lost all my data on a Pegasus RAID box I called R3 Data Recovery. Andy and his team put my mind at rest and said that they were confident that they could recover the lost data. Pegasus had indicated that the information was lost. After a week with R3 they had sent my data (photos from last 10 years) back to me. I was delighted. I can fully recommend R3 Data Recovery and have already done so.”

Specialist RAID Recovery Services
Each RAID level fails in a different way. These pages cover the array types we recover most often, with the failure modes and recovery approach specific to each.
- RAID 0 Data RecoverySpecialist RAID 0 recovery for striped arrays with zero fault tolerance. Single drive failure means total data loss — our engineers reconstruct fragmented data across every disk.
- RAID 1 Data RecoverySpecialist RAID 1 recovery for mirrored arrays — when both drives fail, controllers corrupt, or accidental deletion mirrors across your pair.
- RAID 5 Data RecoverySpecialist RAID 5 recovery for degraded arrays, multiple drive failures, failed rebuilds, and controller corruption across Dell, NetApp, EMC, and Buffalo systems.
- RAID 10 Data RecoverySpecialist RAID 10 recovery for striped and mirrored arrays — when multiple drive failures, controller swaps, or metadata corruption break your hybrid configuration.
Storage systems that share RAID failure modes
NAS and server storage are RAID arrays with extra firmware and filesystem layers on top. Recovery often starts with the same RAID reconstruction steps before the platform-specific work begins.
- NAS Data RecoveryNAS devices from Synology, QNAP, and Buffalo are built around internal RAID arrays — most NAS failures are fundamentally RAID failures with an additional firmware and filesystem layer on top.
- Server Data RecoveryServer RAID arrays — whether hardware controllers from Dell PERC and HP SmartArray or software RAID via mdadm — frequently involve hot-spare misfires, battery-backed cache loss, and multi-array configurations that add complexity beyond the array rebuild itself.
