RAID 10 Data Recovery you can trust
RAID 10 can survive several drive failures, unless both drives in the same mirrored pair fail. Our RAID 10 data recovery service identifies which pairs were affected, recovers the members needed, and rebuilds the stripe — priced per case after a free evaluation.
About raid 10 data recovery
RAID 10 combines mirroring and striping. Drives are grouped into mirrored pairs, and data is striped across those pairs. Each pair holds its own share of the data in duplicate, which gives good performance and lets the array survive the loss of one drive in each pair.
That's why which drives failed matters more than how many. Losing two drives in different pairs leaves a complete copy of everything, while losing both drives in the same pair removes a whole share of the stripe, and the array can't be read without it. Controller and backplane faults can also knock several drives offline at once, and a rebuild that runs in the wrong direction inside a pair can overwrite good data with stale data.
Recovery starts by mapping drives to pairs and pairs to stripe positions. Layouts vary: some controllers build a stripe of mirrors, others a mirror of stripes, and Linux software RAID 10 has its own layout options. Once the layout is known, we pick the best member from each pair and assemble the stripe from those images.
What we recover
- ✓Four-drive and larger RAID 10 arrays
- ✓Server arrays on hardware RAID controllers
- ✓NAS volumes configured as RAID 10
- ✓Linux software RAID 10 and nested RAID 1+0
Common failures we handle
- •Both drives in one mirrored pair failed
- •Multiple drives dropped after a controller or backplane fault
- •Rebuild of a pair copied from the wrong member
- •Array lost its configuration or shows as foreign
Before you send it in: what not to do
- ✕Don't rebuild a pair until you know which member is current — rebuilding in the wrong direction overwrites good data.
- ✕Don't reinitialize the array or let the controller import a foreign configuration without advice — it can rewrite the layout.
- ✕Don't move drives between slots without labeling them — slot positions help identify pairs and stripe order.
- ✕Don't keep running a degraded array where one pair is down to a single drive — if that drive fails, part of every large file is lost.
- ✕Don't run file system repair on a partly failed array — it can write changes based on incomplete data.
How we recover it
Free evaluation and fixed quote
We test every member, gather what you know about the configuration and failure, and give you a fixed quote to approve before work begins.
Image all members
Failed drives are repaired in the cleanroom where needed, and every drive is imaged sector by sector.
Map pairs and layout
Engineers identify which drives mirror each other, the order of the pairs in the stripe, the stripe size, and the offset.
Choose the best member of each pair
Within each pair, we compare members to find the most current, complete copy and fill damaged areas from its partner where possible.
Reconstruct, extract, and verify
The array is assembled virtually from the chosen images, and files are extracted and checked before return.
