Multiple-drive failure
A second weak member can fail during normal operation or a rebuild.
RAID, NAS & server recovery
Stop rebuilds and write access when a storage array fails.
DataDoc assesses failed RAID, NAS and server storage through individual member-drive analysis, controlled imaging and virtual reconstruction. Configuration and drive order must remain preserved.
Important: Switch the affected device off. Do not initialise, format, repair or repeatedly restart the storage medium.
Specialist services
Array recovery starts with the individual drives.
RAID level alone is not enough. Member condition, order, stripe, parity, offsets, rebuild history, volumes and encryption all matter.
Failed rebuild
Wrong order, unreadable members or incorrect parameters can overwrite usable structures.
Lost configuration
Controller, metadata or array parameters can prevent the volume from assembling correctly.
Volume and encryption
Even after array reconstruction, file-system, volume or key material may remain damaged.
Controlled process
Clear steps, documented decisions.
The technical route depends on the device, failure mode, data priority and any previous attempts.
- 01
Stop writes and rebuilds
Shut the system down safely and preserve slot order, labels, logs and configuration.
- 02
Assess every member
Each drive is evaluated individually before any virtual reconstruction is attempted.
- 03
Create working images
Where possible, member drives are acquired to separate storage rather than used directly.
- 04
Reconstruct the array
Order, stripe, parity, offsets, volumes and file system are assembled and verified.

Frequently asked questions
What you should know before sending a device.
Should I start another RAID rebuild?
Not without a sound diagnosis. A rebuild with weak members or incorrect parameters can overwrite recoverable data.
Do you need every member drive?
Usually all member drives and configuration information are required. The exact scope is agreed during intake.
Can DataDoc sign an NDA?
Yes. An NDA can be agreed before detailed technical information or devices are transferred.
Can urgent collection be arranged?
A 24/7 express collection can be requested. Feasibility, timing and price are confirmed in advance.
