RAID 0/1/5/6/10 logical recovery
Parity reconstruction from clones of surviving disks, recovery from filesystem metadata. All RAID levels including stripe + mirror combinations.
Data recovery · server & RAID
Data recovery from RAID, virtualization and NAS — even after a failed rebuild.
RAID 0, 1, 5, 6, 10 — including double-disk failure or aborted rebuild scenarios. VMware VMFS datastores, Hyper-V VHDX virtual disks, Proxmox, Synology and QNAP NAS. Write-blocker policy on original disks; we always work on full clones to preserve the original media.
Twelve documented recovery scenarios.
Scenarios: failed rebuild, double-disk, controller failure
Most common scenarios: rebuild that has worsened the situation, double-disk failure beyond redundancy, controller in fault state with array marked foreign.
Virtualization: VMware VMFS, Hyper-V VHDX, Proxmox
Datastore-level recovery for virtual disks. VMFS structures reconstructed from journal, Hyper-V dynamic VHDX, Proxmox raw and qcow2 images.
NAS Synology, QNAP
Synology Hybrid RAID (SHR), QNAP ZFS pools, ext4 and btrfs on Synology DSM. Recovery starts always from a full clone, never on original disks.
Method: never on originals, always on clones.
Lab policy: original disks received are hardware write-blocked for every operation. Full-disk cloning produces an image on which we operate. Original disks are returned to the client in documented sealed envelope. NDA available on customer request at any point.
FAQ
How quickly can you start a recovery case?
Within 24-48 hours of intake we have an initial assessment with a realistic recovery probability and time estimate. Urgent cases (production blocker) escalated to priority queue within working hours.
Do you guarantee recovery?
No serious data recovery lab guarantees recovery — physical damage to media can make data unrecoverable. We are transparent: after the initial assessment we communicate realistic probability and you decide whether to proceed.
How do you guarantee no writes to original disks?
Lab policy: original disks received are hardware-side write-blocked for every operation. Cloning produces a complete image on which we then work. Original disks returned to customer in a documented sealed envelope.
Do you sign NDAs for sensitive cases?
Yes, we sign mutual NDAs at case opening on customer request. For sensitive sectors (healthcare, finance, defense, certain industrial) NDA is standard procedure on our side as well.
What should I NOT do if my RAID array goes degraded or fails?
Do not start a rebuild if there is any doubt about the integrity of the other disks: rebuilding onto a nearly-failed disk often leads to a second drive failure and array loss. Do not swap disks randomly. Do not run chkdsk/fsck on a suspect volume: it writes to the filesystem and can make recovery harder. Do not unmount and remount disks with the physical order changed unless you have documented it. The right first step is: power off, document, call.
Bring us the disks. We'll bring you back the data.
Each recovery case starts with a 24-48 hour initial assessment: probability, technical method, realistic timeline. No work begins without your explicit go-ahead and a written quote.
