RAID 1 keeps a mirror of your data on a second drive, but both drives can still fail, and a rebuild can copy bad data over good. Our RAID 1 data recovery service finds the healthiest, most current member and recovers from it — priced per case after a free evaluation.
RAID 1 writes the same data to two or more drives, so each member holds a complete copy. That makes it resilient to a single drive failure and also makes recovery comparatively straightforward: one good member is often enough to get everything back, with no striping or parity to rebuild.
The failures we see usually involve more than one problem. A drive drops out of the mirror unnoticed, the array keeps running on the survivor for weeks, and then that drive fails too. Or a rebuild starts from the stale or failing member and copies its errors over the good one. Sometimes members drift apart quietly because of write errors or a controller fault, leaving two copies that each hold different versions of the data.
The key decision in recovery is which member to trust. That means comparing both drives to find which one has the most recent, consistent data, and whether the other can fill in anything the first is missing. It's work done on images of the drives, not on the originals.
What we recover
✓Two-drive mirrors in NAS units and desktops
✓Server boot and data mirrors
✓Hardware, motherboard, and software RAID 1
✓Mirrors with multiple members or hot spares
Common failures we handle
•Both drives in the mirror failed
•A rebuild copied from the wrong or failing drive
•Mirror members silently drifted out of sync
•Array shows as degraded, foreign, or won't mount
Before you send it in: what not to do
✕Don't start a rebuild if you're unsure which drive is good — rebuilding in the wrong direction overwrites the current data.
✕Don't put the old drive back into the array — re-adding a stale member can trigger a rebuild that replaces newer data.
✕Don't run disk repair tools on both members — if one holds the good copy, keep it untouched.
✕Don't reinitialize the mirror or create a new array on the same drives — it can overwrite the existing metadata and data.
✕Don't keep running the array on its last working drive — if it fails too, recovery gets much harder.
How we recover it
1
Free evaluation and fixed quote
We test each member, review the array history you can share, and give you a fixed quote to approve before work begins.
2
Image every member
Each drive is repaired in the cleanroom if needed and imaged sector by sector, so the originals aren't changed further.
3
Compare members and pick the source
Engineers compare the images to find which member holds the most recent, consistent data, and identify sections where the other member is the better source.
4
Repair and extract
We repair the file system on the chosen image, fill gaps from the other member where possible, then extract and verify your files.
Multi-drive cases are quoted per job after a free evaluation — the price depends on the configuration, the failure, and the work involved. There's no charge for the evaluation, and you pay nothing unless we recover your data.
Isn't RAID 1 already a backup?+
No. A mirror protects against a single drive failing, but it copies deletions, corruption, and ransomware to both drives instantly. A separate backup is still needed.
Both drives in my mirror failed. Is the data gone?+
Not necessarily. Each member holds a full copy, so if either drive can be repaired and imaged, that may be enough. Sometimes damaged areas on one drive can be filled in from the other.
A rebuild went wrong. Can you still recover?+
It depends on how far the rebuild got and which direction it ran. Stop the array and send both drives. Data that hasn't been overwritten on the good member may still be recoverable.
Should I send both drives or just the one that failed?+
Send both, labeled with their slot positions. Even the drive that seems healthy may be the one with the better copy, and comparing them is part of the recovery.
Is my data still recoverable?+
In most cases, yes. A device that won't boot or mount usually has a hardware fault while the data itself is intact. The key is to stop using it — don't reformat, rebuild, or keep powering it on — and let our cleanroom handle it.
How do I send in a RAID 1 system?+
Start online for a free evaluation and we'll arrange secure, insured shipping. Your system is assessed in our cleanroom, you approve a fixed quote before any work, and you only pay on a successful recovery.
How long does it take?+
Most cases are evaluated within a couple of business days of arrival, with a turnaround estimate provided alongside your quote. Emergency service is available when time is critical.
