Maidenhead Data Recovery – No.1 RAID 0 Data Recovery Specialists (25+ Years)

RAID 0 is performance-only, zero-redundancy. A single bad disk, cable, or controller glitch can take the whole volume down. Our engineers specialise in catastrophic, no-parity recoveries across home, SMB and enterprise environments—covering software RAIDs, hardware controllers, NAS, large NAS, and rack systems.

How we recover RAID 0 (no parity)

Key constraint: RAID 0 has no redundancy. Full recovery requires every member’s data (or repairing a failed disk enough to image it). Our workflow:

1. Forensic intake & preservation

   • Photograph, label bay/port order; record controller metadata.

   • Quarantine originals; all work is from sector-level clones.

2. Per-disk stabilisation & cloning

   • HDD: electronics/SA checks, adaptive head-map imaging (PC-3000/DeepSpar/Atola), timeouts, reverse passes, read-retry windows.

   • SSD/NVMe: vendor-mode reads, error log checks, throttled thermal profile, ECC-aware imaging.

   • If a member has mechanical failure: donor HSA/PCB transplant, short-duty imaging to capture critical LBA ranges first.

3. Stripe reconstruction

   • Identify/verify stripe size, start offset, disk order/rotation (left/right, synchronous/asynchronous), and any controller metadata shifts.

   • Build a virtual RAID from the clones; validate with filesystem anchors (NTFS boot, EXT4 superblock, APFS container, XFS super, etc.).

4. Logical repair & extraction

   • Mount read-only; repair filesystem structures (MFT/Catalog/B-trees/journals).

   • For VMs/databases: extract VMDK/VHDX, LUNs; then recover guest files.

5. Verification & hand-off

   • Hash manifests, sample-open critical assets, secure transfer.

Top 40 RAID 0 failures we handle – and how we fix them

In RAID 0, a “failure” is often any fault on any member. Below are common technical cases and our recovery approach.

1. Single-disk mechanical failure → Donor head-stack or PCB; capture adaptives/ROM; head-map imaging prioritising metadata zones; complete clone → re-stripe.

2. Single-disk spindle seizure → Platter/hub transplant to matched chassis; low-duty clone; integrate into stripe set.

3. Intermittent head (weak channel) → Per-head imaging with tuned timeouts; reverse/short-skip passes; fill late → assemble.

4. Surface media damage → Multi-pass reads, adaptive windowing; generate bad-block map; accept partials and reconstruct files not spanning lost LBAs.

5. Electronics (TVS/regulator/MCU) → TVS isolation, regulator swap, donor PCB with ROM transfer; image.

6. Drive firmware SA/translator issues → Module patching, translator regen, suppress background tasks; stabilise reads.

7. SSD controller brick (enumeration fail) → Vendor/test-mode access; if feasible NAND dump+FTL rebuild (not for T2/Apple-soldered).

8. SSD/NAND high BER/retention → ECC/LDPC soft-decode, voltage/temperature tuning, multiple-read voting → usable clone.

9. Cable/backplane intermittency → Bypass chassis; direct-attach to HBA; image cleanly, ignoring controller dropouts.

10. Wrong disk order after removal → Stripe analysis (parity-less heuristics + FS anchors) to determine order/rotation/offset; re-assemble.

11. Unknown stripe size → Test common sizes (16–1024 KiB) with autocorrelation against filesystem structures; lock when consistent.

12. Controller metadata offset → Detect and strip controller headers/trailers; align real data region; re-build virtual array.

13. Foreign import wrote new labels → Virtually mask new labels; recover pre-existing layout via signature search; assemble.

14. Accidental initialise/new RAID created → Most user data remains; scan members for previous FS anchors; reconstruct original stripe geometry.

15. Online capacity expansion (OCE) aborted → Determine migration boundary; build composite image (pre-OCE geometry then post-OCE geometry); extract.

16. Platform migration misalignment → Adjust start LBA/stripe boundary (“slide”) until FS boots; validate with directory trees.

17. JBOD treated as RAID 0 → Identify contiguous span vs interleaved layout; if true JBOD, concatenate members in order; recover.

18. RAID 0 over mixed sector sizes (512e/4Kn) → Normalise logical sectoring in virtual assembly; fix off-by-alignment corruption.

19. Host cache/power-loss write-tear → Expect FS journal damage; after assembly, run safe logical repair; salvage unaffected extents.

20. Bad sectors on multiple members → Clone with error maps; identify files spanning overlapping bad stripes (report partial risk); recover remainder fully.

21. USB bridge quirks (NAS/DAS enclosures) → Remove from bridge; direct SATA/SAS imaging; ignore enclosure-level LBA remap.

22. Bit-locker/Volume encryption on top → Assemble RAID; decrypt with client keys; then repair filesystem inside.

23. APFS container spanning the stripe → Validate NXSB checkpoints; rebuild B-trees; mount RO; export volumes.

24. NTFS $MFT/$LogFile damage → Rebuild MFT from mirror, $Bitmap; carve as fallback; preserve paths/timestamps where possible.

25. EXT4 superblock/journal corruption → Use backup superblocks; journal-aware replay; extract.

26. XFS log corruption → xfs_repair on clone (with -L if needed); integrity check; export.

27. Mac Fusion-like tier misidentified as RAID 0 → Identify SSD/HDD pairing; reconstruct logical tier rather than stripe; recover.

28. NVMe stripe in workstation → Throttle thermal, fixed QD; image each NVMe; rebuild in software mapper.

29. Dropped disk replaced (new data written) before failure → If prior member retained, prefer its clone; reconcile divergent regions by FS integrity.

30. Controller firmware bug (mis-stripe) → Detect periodic mis-rotation; correct mapping rules in virtual layer; rebuild sequence.

31. Sector remap storms (pending/reallocated) → Stabilise with low-queue sequential reads; avoid forced writes; capture pre-failure state.

32. Silent data corruption (no checksums) → Post-assembly FS validation; compare duplicate structures (e.g., MFT/Mirr); flag suspect files.

33. Snapshot/lun inside RAID 0 → Reassemble base stripe → mount VMFS/ReFS/LVM; then extract VMDK/VHDX/LVs.

34. Sparse/fragmented large files (video/DB) → After assembly, reconstruct containers (MP4 moov rebuild, SQLite/WAL merge, DB repair).

35. Monolithic USB/NVMe used as stripe member → Expose pads/vendor mode; raw dump; normalise into member image; join stripe.

36. Mixed firmware revisions across identical models → Per-member quirk handling (e.g., read-timing windows); avoid cross-polluting adaptives.

37. NAS mdraid “RAID 0” with md metadata → Remove md superblocks from virtual view; reconstruct pure interleave.

38. Wrong logical block size reported by one member → Force consistent LBS in mapper; re-index stripe math.

39. Filesystem resized across stripe then failed → Identify new FS extent layout; mount largest coherent subset; harvest.

40. User attempted software recovery (wrote to disks) → Diff clones vs backups/undo logs; roll back clobbered regions where provable; otherwise carve.

What to do right now

• Power down the array. Don’t re-initialise or rebuild.

• Label drive order/slots; package each in anti-static sleeves and a small padded box.

• Post or drop off to us with your contact details and a brief symptom summary.
