RAID & Server Data Recovery
We evaluate failed RAID arrays, NAS enclosures, and enterprise SAN storage. For business-critical situations, contact us about priority-service availability. Recovery timing depends on the diagnosis, drive condition, and array complexity.
Do not attempt a RAID rebuild. Failed rebuilds permanently destroy parity data and are the #1 cause of unrecoverable RAID failures. Power off and call us first.

RAID Configurations We Recover
Every RAID level has a different failure profile and recovery approach. We handle them all.
Striping — maximum speed, no redundancy. A single drive failure causes total data loss. We reconstruct stripe sets from remaining drives.
Mirroring — data written identically to two drives. Recovery focuses on the healthier mirror when both fail simultaneously.
Striping with parity — the most common enterprise configuration. We recover from single and sometimes double-drive failures by reconstructing parity.
Dual parity — tolerates two simultaneous drive failures. We recover from triple-drive failure scenarios using advanced parity reconstruction.
Stripe of mirrors — combines speed and redundancy. We recover from multiple mirror failures using the surviving members of each mirrored pair.
Network-attached storage running RAID over consumer or prosumer hardware. We recover from NAS arrays regardless of the proprietary filesystem (Btrfs, ext4).
Enterprise storage area networks with Fibre Channel or iSCSI. We work with IBM, EMC, NetApp, and HP enterprise SAN hardware.
Linux-based software RAID using mdadm. We reconstruct degraded arrays and recover from failed builds that left the array in an inconsistent state.
Emergency Service
For a business-critical server failure, call (840) 999-1034 to discuss priority evaluation, current availability, and applicable fees. We estimate turnaround after reviewing the case.

FAQ
Can RAID 5 data be recovered with two failed drives?
RAID 5 is designed to survive one failed drive. With two failures, data is technically lost from the array. However, if the second drive has a logical failure (not physical), we can sometimes image it and reconstruct enough parity to recover data. We evaluate each case individually.
My NAS won't rebuild — can I still recover the data?
Yes. Failed rebuilds are one of the most common RAID recovery scenarios. We image every drive in the array individually before attempting any reconstruction, protecting you from making the situation worse. We then reconstruct the array virtually in our lab.
How long does RAID recovery take?
Depending on the number of drives and their health, RAID recovery takes 3–10 business days. Large arrays with physical drive failures take longer. Emergency rush service is available for business-critical situations.
How much does RAID data recovery cost?
RAID recovery pricing depends on the device and required service and scales based on the number of drives, array type, and the extent of physical damage. Multi-drive arrays with physical failures will be higher. We provide a firm quote after imaging all member drives.
Should I try to rebuild the RAID myself?
No — this is the most common way data is permanently lost. A failed rebuild overwrites parity data and can destroy the array. Power it off, stop all access, and bring it to us. We image every drive first before touching the array configuration.
