RAID Recovery
A failed array is rarely a single-disk problem. AS images every member disk, reconstructs the array virtually, and recovers from the reconstruction so the originals are never rebuilt or written to.
When you need this
- Multiple disks failed and the array is offline
- Rebuild started or completed onto the wrong disk
- Controller failed or configuration was lost
- Array reports healthy but volumes are unreadable
- Accidental re-initialisation or reconfiguration
- Ransomware on a RAID-backed server
What we do
Member disk imaging
Each disk is imaged independently, including failing members, so recovery works from copies.
Virtual reconstruction
Stripe size, disk order, parity rotation and offsets are determined and the array is assembled virtually — including custom and vendor-specific layouts.
Volume and file system recovery
Volumes, LVM/Storage Spaces layers and file systems are recovered from the reconstructed array.
Stale-member analysis
Where disks dropped out at different times, we identify which members hold current data to avoid mixing old and new blocks.
How it works
- Step 1
Consultation and scope
We establish what failed, what has been tried, and which data matters most. This shapes a targeted plan rather than a generic one.
- Step 2
Secure imaging and diagnosis
Where possible the source media is imaged before any work, so the original is never altered. Diagnosis then determines the safest recovery method.
- Step 3
Recovery
Data is extracted from the image or source using methods matched to the failure — logical, structural or hardware-level as required.
- Step 4
Verification
Recovered data is checked for integrity and completeness, and a file list is shared so you can confirm what matters is there.
- Step 5
Secure delivery
Verified data is returned through an agreed secure method, with guidance on validation before it goes back into production.
What affects the outcome
Outcomes are never guaranteed. Every case is assessed on its own condition, and we tell you what is realistic before you commit.
- Physical condition of the media and the extent of any damage
- Whether the media has been written to, reformatted or re-initialised since the failure
- Encryption, corruption or partial overwriting of the data
- Availability of source data such as images, backups, logs or transaction records
- Attempts made before assessment (rebuilds, repair tools, repeated reboots)
AS RAID Recovery
For arrays with healthy disks and a lost configuration, the software can reconstruct the array and recover data on your own hardware.
Frequently asked questions
Should I let the controller rebuild the array?
Not before assessment. A rebuild with a stale or failing disk can overwrite good data permanently. Power down and preserve the disks as they are.
Do you need the RAID controller?
Usually not; the array is reconstructed from the member disk images. Controller details help but are rarely required.
Can you recover a RAID 0 with one dead disk?
Only if data can be extracted from the failed disk. RAID 0 has no redundancy, so the outcome depends on that disk's condition.
