Failed RAID rebuilds
Arrays that degraded, failed during rebuild, dropped another disk, or became inaccessible after a drive replacement.
RAID & NAS data recovery
RAID & NAS data recovery in North York for failed arrays and storage systems.
OmniData recovers business files, shared folders, photos, backups, and database storage from failed RAID arrays, NAS devices, servers, and external RAID enclosures. Each drive is handled individually before the array is rebuilt virtually.
RAID failure types
RAID and NAS problems we handle
RAID recovery is not just a file scan. The drive order, stripe size, parity rotation, filesystem, and condition of each disk can determine whether the data can be reconstructed safely.
Multiple drive failure
RAID sets with bad sectors, clicking drives, slow drives, firmware problems, or disks that no longer detect properly.
NAS volume corruption
Synology, QNAP, and other NAS volumes that will not mount, show missing shared folders, or report corrupted storage pools.
Deleted or formatted data
Deleted shares, formatted volumes, accidental initialization, damaged partition tables, and lost business folders.
Important
Before bringing in a failed RAID or NAS system
Do not initialize, rebuild, or replace more drives.
Rebuild attempts can overwrite parity, metadata, or filesystem structures, and they can put heavy stress on weak disks. If a RAID or NAS is already degraded, every additional rebuild attempt can reduce the chance of a clean recovery.
Bring every drive that belongs to the RAID, including failed drives.
Removed, failed, slow, or non-detecting drives can still contain critical parity, metadata, or file data needed to rebuild the array. Do not leave any original RAID member behind, even if the NAS or server marked it as failed.
Read the RAID failure warning guideWhat to do now
Keep the drives in their original order.
Power the system down, label each drive by bay number, and avoid filesystem utilities such as chkdsk, fsck, or NAS rebuild prompts on the original disks. The safest recovery path is to image every drive first, then reconstruct the array from the copies.
Lab process
How RAID & NAS recovery works
01
Document the array
We record drive order, NAS model, RAID level, failure history, and any rebuild or recovery attempts before work begins.
02
Image each drive
Every disk is assessed and cloned individually, with controlled handling for weak, slow, or failing drives.
03
Rebuild the array virtually
The RAID parameters and NAS filesystem are reconstructed from images, so the original disks are not changed.
04
Verify and return files
Recovered data is checked, organized, and returned securely after approval.
In-house RAID recovery
RAID recovery starts with the drives, not the rebuild button.
These photos show real RAID and NAS recovery context, controlled imaging, and in-house diagnostics inside the OmniData workflow.
RAID & NAS FAQ
Questions people ask before bringing in a failed array.
Can data be recovered after a failed RAID rebuild?
Often, yes. The safest approach is to stop all rebuild attempts, image each drive, and reconstruct the RAID virtually so the original disks are not modified further.
Should I replace another drive and try rebuilding again?
No. If the first rebuild failed or the array is unstable, another rebuild can overwrite important data and stress weak drives. Power the system down and have the drives assessed first.
Do you recover Synology and QNAP NAS systems?
Yes. OmniData handles Synology, QNAP, and other NAS systems with failed storage pools, corrupted volumes, deleted shares, and degraded RAID arrays.
Do you need all of the drives?
Bring every drive from the array whenever possible, even drives that seem failed or were removed earlier. The original drive order and full disk set can be critical for reconstruction.
