IN-LAB – NO OUTSOURCING – KING OF PRUSSIA, PA

⚠️ Stop the rebuild. Don’t force a drive back online. Rebuilding a degraded array puts heavy read/write stress on every remaining drive and can overwrite recoverable data — a second failure during rebuild is the single most common cause of total RAID data loss. Power down and call us before taking any further action.

THE DIFFERENCE IS CLEAR

Why Tri-State Data Recovery vs. Everyone Else

RAID recovery is the most technically demanding service in this industry — and the easiest to get wrong. Most IT consultants and national chains don’t have the in-house capability to rebuild a complex array; they outsource it.

PC SHOPS & NATIONAL CHAINS
✗ Ship your entire array — every drive, your company’s complete dataset — to an out-of-state lab
✗ Attempt a live rebuild on production hardware, risking a second drive failure mid-process
✗ Guess at stripe size, parity rotation, and drive order rather than verifying them
✗ Limited experience beyond basic hardware RAID — NAS firmware and virtualized arrays are out of scope
✗ Hidden markups on outsourced lab fees; surprise invoices after the fact
✗ No documentation trail if litigation or compliance review follows the data loss event
TRI-STATE DATA RECOVERY
🗹 RAID rebuild and recovery performed entirely on-site at our King of Prussia lab — never outsourced
🗹 Every member drive is imaged first using specialized hardware designed for failing drives; all reconstruction happens on cloned data, never the originals
🗹 Full parameter discovery — stripe size, parity order, disk order, and offset confirmed before extraction
🗹 Experience across hardware RAID, software RAID (mdadm), NAS firmware, and virtualized arrays (VMware, Hyper-V)
🗹 Transparent flat-rate diagnostic; phone call with a firm quote before any work begins
🗹 HTCIA member with forensic capabilities & full chain of custody: court-ready reports & expert witness testimony

EVERY RAID CONFIGURATION

We Recover Every RAID Level

Each RAID level fails differently and carries different recovery odds. Here’s what we see most often, and how exposed each configuration really is.

RAID 0

Striped Array

No redundancy. A single drive failure takes down the entire array, and data is fragmented across every remaining disk. Recovery is possible only if all member drives are still intact and the original stripe parameters can be determined.

Highest Risk

RAID 1

Mirrored Array

Tolerates failure of all but one drive in the mirror. Most common failure pattern: one drive silently fails and goes unnoticed for months, then the second drive fails — eliminating redundancy entirely without warning.

Lower Risk

RAID 5

Distributed Parity

Survives one drive failure. The danger is the rebuild itself — on modern multi-terabyte drives, rebuilds can take many hours, and a second failure during that window destroys the array completely.

Rebuild-Vulnerable
Database Database

RAID 6

Dual Parity

Survives two simultaneous drive failures — a meaningful upgrade over RAID 5. We commonly see failed rebuilds on RAID 6 from large-capacity drives, where the rebuild stresses already-aging remaining disks.

Moderate Risk
Database Database

RAID 10

Mirrored + Striped

Combines mirroring and striping for speed and redundancy. Can survive multiple drive failures — but only if they occur in separate mirror pairs. Losing both drives in a single pair causes full data loss.

Lower Risk
Database Database

RAID 50/60

Nested Arrays

Multiple RAID 5 or RAID 6 groups striped together for large-scale storage. Recovery requires correctly identifying both the sub-array configuration and the outer striping layer — a two-layer reconstruction problem.

Complex Reconstruction

OUR RECOVERY PROCESS

How We Recover Your RAID, NAS & SAN

RAID recovery is fundamentally a reconstruction problem, not a single-drive repair. Our process is built around verifying every array parameter before a single byte of data is extracted.

𝟏

Image Every Drive

Every member drive — including failed ones — is sector-cloned first. All reconstruction happens on the clones. Your original drives are never written to or put at further risk.

𝟐

Parameter Discovery

We determine RAID level, stripe size, parity rotation, disk order, and offset — even if your controller configuration was lost, corrupted, or never documented.

𝟑

Virtual Array Rebuild

We reconstruct a virtual RAID set from the drive images using the verified parameters — without touching your physical hardware or risking the original array.

𝟒

File System Repair

Once the virtual array mounts cleanly, we address file system-level damage — NTFS, ext4, XFS, ZFS, Btrfs, HFS+, or APFS — depending on your server or NAS platform.

𝟓

Verification & Transfer

Recovered data is verified for integrity and transferred to new drives or a replacement system. You review the results before final payment.

COMMON RAID & SERVER FAILURES

We Recover Data From Every Type of Array Failure

A RAID array can fail in ways a single drive never could. Here are the failure patterns we handle most often.

Cancel-circled Cancel-circled

Failed Rebuild

A drive was replaced and the rebuild process hit a second failure — a read error, a weak drive, or a power interruption mid-rebuild. The array is now offline with the rebuild incomplete and potentially corrupted.
Attention Attention

Multiple Drive Failure

More drives have failed than your RAID level’s fault tolerance allows — two drives down on RAID 5, three on RAID 6, or both drives in a single RAID 10 mirror pair.
Cog Cog

Controller Failure

The RAID controller — hardware or software — that manages the array has malfunctioned or become corrupted. The array is no longer visible to the system even though the member drives are healthy.

Drive Order Lost

A chassis move, backplane swap, or hot-swap accident scrambled the physical drive order. The array shows as unformatted, RAW, or won’t mount — even though every drive is intact.

Power Surge & Cache Loss

A surge or improper shutdown corrupted the controller’s NVRAM or battery-backed write cache, leaving in-flight writes lost and array metadata inconsistent.

File System Corruption

The RAID structure itself is intact, but the file system on top of it — NTFS, ext4, XFS, ZFS — has corrupted metadata, a damaged journal, or a failed checksum, blocking access to the data.

IF YOUR ARRAY JUST FAILED

What To Do — and What Not To Do — Right Now

The actions taken in the first hour after a RAID failure often determine whether the data is recoverable at all.

🛑 Don’t
✗ Force a "stale" or failed drive back online — it can introduce outdated data and corrupt the entire array
✗ Re-run the controller’s initialize or re-create array function if the data matters
✗ Continue a rebuild after a second drive shows errors or drops offline
✗ Swap drives without labeling the original bay/slot order first
✗ Run consumer recovery software directly against a degraded array
✓ Do
🗹 Power down the system to stop further stress on the remaining drives
🗹 Label every drive with its bay/slot number before removing anything
🗹 Record your RAID level, drive count, and any error codes or controller alerts
🗹 Leave drives in their original order if at all possible
🗹 Call before attempting any further troubleshooting steps

What Our Clients Say About Server & RAID Recovery

4.9 stars across 300+ Google & Facebook reviews. Businesses trust us with their most critical infrastructure.

⭐⭐⭐⭐⭐

“I am the CIO at a Public School in Kentucky. Our main server crashed and all of the teacher and student data was on there. I googled Data Recovery and Don Anderson’s site came up close to the top and it looked very professional. I sent him my 6 Drives and he had an external drive back to me in less than 5 days with all of my data! I could not be happier and neither could my students and teachers. I would recommend him to anyone.”

⭐⭐⭐⭐⭐

“Short: Don is excellent at his job. Recovered everything lost on two old RAID 0 mechanical drives that had been fried by a power surge. Would recommend to anyone who would like to retrieve lost data.

Long: Don went through a huge amount of effort with my drives that presented a particular challenge. Don had to fix the original issue the power surge caused, problems another data recovery place caused, and returned the damaged drives in working condition. After recovering the data it was transferred to an external drive included in the price he gave. When I arrived to pick it up he gave me time to look through the data he recovered so that I could verify everything was there. Don truly knows what he is doing I would recommend his services for any size job. His prices are fair, he is professional, and just seems like a nice guy. He will also offer you help if you need it setting up a better backup solution.”

“I had a main drive failure on my server at one of my stores. Don did a great job of retrieving the lost data and we were up and running in less than 24 hours. They were fast, professional and did a great job.”

Howard Anderson
President, Stony Brook Sew and Vacuums, Inc.

⭐⭐⭐⭐⭐

“We were in the middle of a network upgrade when one of my main storage servers decided to up and die on us. The server contained a lot of archived files as well as some profiles which would have been very difficult to replace. Don brought back all of the data which I was convinced was lost forever.”

⭐⭐⭐⭐⭐

“I called Don in an absolute panic. Our business lost ALL of its data on a RAID hard-drive configuration. I explained the severity of the situation. He promised he would work day and night to recover our data, and he did. If it were not for Don, I would have lost 2 years of work.”

FREQUENTLY ASKED QUESTIONS

RAID & Server Data Recovery FAQ

In many cases, yes. While RAID 5 only tolerates one drive failure during normal operation, a second failed drive doesn’t necessarily mean total loss. We image every drive — including the failed ones — and use specialized hardware imaging tools to read around bad sectors. Depending on the failure pattern, data on the surviving sectors can often still be reconstructed even beyond the array’s standard fault tolerance.

Not necessarily. A failed rebuild usually means a second drive hit errors during the resync process, but the original data on the array’s other drives is typically still intact. We stop any further rebuild attempts, image all member drives in their current state, and reconstruct the array virtually from those images — without risking further damage to the originals.

Yes. This is one of the most common situations we handle. We perform full parameter discovery on the imaged drives — determining RAID level, stripe size, parity rotation, and disk order through analysis rather than relying on documentation that may be lost or wrong. Guessing at these parameters yourself is one of the fastest ways to make an array unrecoverable, so it’s important this step is done correctly.

Yes. Most NAS failures are fundamentally RAID failures with a proprietary firmware and file system layer on top. We work with Synology’s and QNAP’s RAID implementations directly, as well as DROBO’s proprietary BeyondRAID technology, which uses a different data layout than standard RAID and requires its own reconstruction approach.

Yes. Virtualized storage adds a layer of complexity — the underlying physical RAID array has to be reconstructed first, and then the virtual disk format (VMDK, VHD/VHDX) on top of it has to be parsed and repaired. We handle both layers, recovering data from VMware ESXi datastores and Hyper-V virtual machines built on failed RAID storage.

No — every additional attempt to mount, rebuild, or run repair tools against a degraded array increases the risk of permanent data loss. The single most damaging action is forcing a “stale” drive back online, which can introduce outdated or corrupted data across the entire array. Power the system down, label your drives, and contact us before taking further steps.

Diagnostics on multi-drive arrays typically take longer than single-drive cases due to the number of drives that need to be imaged and analyzed. Once parameters are verified and reconstruction begins, timelines depend on array size and failure complexity — simple cases may complete within a few business days, while large arrays with physical drive damage can take longer. We provide a realistic timeframe with your quote, and emergency/expedited service is available for business-critical cases where we will work around the clock until completion.

Yes. General IT providers and consultants typically don’t have dedicated RAID reconstruction tools or experience with complex multi-drive failures — “unrecoverable” from them usually means “beyond what we’re equipped to attempt.” They advertise “Data Recovery Services” because the industry is not regulated and they are allowed to push clients into their unethical outsourcing program which offers them commission while violating HIPAA and risks data theft.  We regularly recover arrays that were declared a total loss elsewhere.
