What Professional RAID Data Recovery Services Include

RAID data recovery is built around accurate reconstruction of your RAID set so your data becomes readable again, even after multiple faults.

  • RAID array reconstruction with correct parameters

    We identify stripe size, parity order, disk order, offset, and rotation, then rebuild a virtual RAID group for safe extraction.

  • Support for common and complex RAID levels

    We recover RAID0, RAID1, RAID5, RAID6, RAID10, RAID50, RAID60, and RAIDZ variants, including nested and parity based arrays.

  • Work from images, not live disks

    We clone member disks at sector level, verify read errors, and keep originals write protected to prevent overwrite and further corruption.

  • Filesystem and metadata repair

    We repair NTFS, ReFS, ext4, XFS, Btrfs, ZFS, HFS plus, APFS, and VMFS issues by parsing MFT, inodes, journals, superblocks, and allocation bitmaps.

  • Encrypted and virtual workloads handled

    We can recover data from BitLocker, LUKS, and VeraCrypt volumes when keys are available, plus SAN LUNs and VM disk containers when metadata is damaged.

  • Talk to an engineer about your RAID issue

    If your RAID array has failed or is unstable, our engineers are available 24/7 to review your situation and advise on next steps.

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.

  • Array shows degraded, then fails during rebuild

    A RAID5 or RAID6 rebuild can hit a second read error, leaving the volume offline. You may see pending sectors, reallocated sectors, or SMART warnings across member disks.

  • 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.

  • 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.

  • 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. You may see orphaned directories, missing files, or truncated data.

  • 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, making data look deleted or overwritten.

When to stop: RAID data recovery should start once you see repeated read errors, a failed rebuild, clicking drives, or volumes flipping between online and offline. Continued use can overwrite parity and metadata.

How RAID Data Recovery Works: From Diagnosis to Final Verification

RAID data recovery is a controlled process that protects original media, reconstructs the RAID set, and restores data to safe storage.

  1. 1

    Triage and intake

    We record symptoms, RAID level, enclosure model, controller type, and recent events like rebuild, scrub, power loss, or firmware update.

  2. 2

    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.

  3. 3

    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.

  4. 4

    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.

  5. 5

    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.

RAID Recovery Questions About Risk, Timing, and Data Safety

RAID data recovery is a service that rebuilds or reconstructs a RAID array to make files accessible again after disk failure, corruption, or misconfiguration.

How does RAID data recovery work if a disk is missing?

RAID data recovery can often reconstruct RAID5 with one missing disk and RAID6 with up to two missing disks, if remaining members read consistently and parity blocks validate.

Can you recover data after an accidental reinitialise or reconfigure?

RAID data recovery can often retrieve data after a controller initialise or reconfigure when the bulk data blocks remain intact. We scan for old metadata, reconstruct layouts, and verify filesystems.

Do you recover from hardware RAID and software RAID?

Yes. We handle hardware RAID controllers and software RAID setups such as mdadm, LVM on top of RAID, Windows Dynamic Disks, and Storage Spaces.

How long does RAID Data Recovery take?

Time depends on capacity, number of disks, read speed, and the count of bad sectors. Imaging and reconstruction often take longer than extraction, especially on large RAID 6 and RAID 60 sets.

Can you recover encrypted RAID data?

Yes, when you provide the encryption key or passphrase. We reconstruct the RAID layout first, then decrypt and restore files after we verify the volume structure.
