Hard Drive Data Recovery

Seagate Exos Data RecoveryST10000NM0016 / ST12000NM0007 / ST16000NM001G

Seagate Exos enterprise drives use helium-sealed enclosures at higher capacities. Opening one releases the helium and permanently alters head flight characteristics. Recovery requires specialized approaches different from standard atmospheric drives. We recover Seagate Exos drives using our PC-3000 system's Seagate (SAS variants require PC-3000 SAS hardware) module at our Austin lab.

Helium-Sealed Drive: Cannot Be Opened in Normal Atmosphere

Seagate Exos drives at higher capacities are sealed with helium. Opening the drive releases the helium and permanently changes head flight characteristics. Traditional head swap procedures do not apply to helium-sealed models.

Recovery Feasibility

PC-3000 Supported
Extreme Complexity

Helium-sealed; opening destroys the drive. Recovery requires helium-atmosphere equipment or alternative approaches. Currently limited head swap options for helium drives.

Model Numbers

The following model numbers belong to the Seagate Exos family. Check the label on your drive to confirm it matches one of these models before referencing the failure modes below.

Failure Modes

Each failure mode requires a different diagnostic approach and recovery technique. Identifying the correct failure is the first step before any work begins.

Helium seal compromise

Helium-sealed drives cannot be opened in normal atmosphere. Heads no longer fly correctly without helium. up to 10 platters in 20TB+ models.

Symptoms you may notice

  • Drive not spinning
  • Unusual noises
  • Sudden failure in server

SAS dual-port complexity

SAS dual-port adds recovery complexity. Requires PC-3000 SAS hardware for SAS variants.

Symptoms you may notice

  • SAS drive not detected
  • Drive removed from server array
  • Enterprise drive failure

Head Swap and Donor Matching

Donor Requirements

Helium-sealed; opening destroys the drive. Recovery requires helium-atmosphere equipment or alternative approaches. Currently limited head swap options for helium drives.

We maintain a donor drive inventory at our Austin lab and can source additional donors when needed. Head swaps are performed in our ISO Class 5 clean bench environment.

Recording Technology

This drive uses Conventional Magnetic Recording (CMR). Each track is independent, making sector-by-sector imaging more predictable than SMR drives. Write operations do not affect adjacent tracks.

CMR simplifies recovery because there is no media cache layer to reconstruct. The data layout on the platters directly mirrors the logical block addresses.

How We Recover Seagate Exos Drives

Firmware-Level Recovery

We use the PC-3000 with the Seagate (SAS variants require PC-3000 SAS hardware) module for firmware diagnostics and repair. This handles translator corruption, service area damage, and firmware boot failures.

Firmware recovery preserves the original head assembly and avoids the risks of a donor swap. For Seagate Exos drives with firmware corruption, this is the first recovery path we attempt.

Physical Recovery (Helium Drives)

Helium-sealed drives cannot be opened in normal atmosphere for traditional head swap. The heads are designed to fly on helium, which is less dense than air. Recovery depends on firmware-level access or manufacturer-level tools.

If the heads have physically failed, recovery options are limited. We evaluate each case individually and provide an honest assessment of what is possible before any work begins.

Pricing

Logical and firmware recovery for Seagate Exos drives typically costs $300 to $600. Head swap cases requiring a donor drive run $600 to $1,500 depending on head count and donor availability. Helium-sealed drive recovery is $1,500 to $3,000 due to the specialized techniques required.

See our full pricing breakdown for details. Our No Data, No Fee guarantee means you pay nothing if we cannot recover your files.

Hard Drive Data Recovery Standards & Verification

Our Austin lab operates on a transparency-first model. We use industry-standard recovery tools, including PC-3000 and DeepSpar, combined with strict environmental controls to make sure your hard drive is handled safely and properly. This approach allows us to serve clients nationwide with consistent technical standards.

Open-drive work is performed in a laminar-flow bench filtered to 0.02 µm, verified using TSI P-Trak instrumentation.

Transparent History

Serving clients nationwide via mail-in service since 2008.

Media Coverage

Our repair work has been covered by The Wall Street Journal and Business Insider, with CBC News reporting on our pricing transparency. Louis Rossmann has testified in Right to Repair hearings in multiple states and founded the Repair Preservation Group.

Aligned Incentives

Our "No Data, No Charge" policy means we assume the risk of the recovery attempt, not the client.

Louis Rossmann

Louis Rossmann's well trained staff review our lab protocols to ensure technical accuracy and honest service. Since 2008, his focus has been on clear technical communication and accurate diagnostics rather than sales-driven explanations.

We believe in proving standards rather than just stating them. We use TSI P-Trak instrumentation to verify that clean-air benchmarks are met before any drive is opened.

Frequently Asked Questions

What does helium-sealed mean for data recovery?
Seagate Exos drives at higher capacities (10TB+) are filled with helium instead of air. Helium is less dense, allowing the heads to fly closer to the platters and enabling up to 10 platters in a single drive. Opening the enclosure releases the helium permanently. Once the helium is gone, the heads no longer fly at the correct height and the drive cannot function. Recovery requires specialized approaches different from standard atmospheric drives.
Can you recover data from a SAS Exos drive?
Yes. SAS (Serial Attached SCSI) variants of the Exos use dual-port interfaces that require PC-3000 SAS hardware, which is a separate module from the standard SATA setup. We have the SAS hardware needed to connect to and image these drives. SAS drives are typically found in enterprise servers and storage arrays, so we also handle any RAID reconstruction needed.
Why are Exos drives so complex with up to 10 platters?
The 20TB+ Exos models pack up to 10 platters with up to 20 read/write heads in a single enclosure. More platters means more components that can fail, more precise alignment requirements during any head swap, and a helium seal that cannot be broken without consequences. The sheer component count makes physical recovery significantly more involved than a standard 2-3 platter desktop drive.
Do you handle server and datacenter drive recovery?
Yes. We recover Exos drives pulled from Dell PowerEdge, HPE ProLiant, Supermicro, and other enterprise servers. We handle single drive recovery as well as multi-drive RAID array rebuilds. If your server uses hardware RAID, we can reconstruct the array from individual drive images regardless of the RAID controller brand.
How much does Seagate Exos enterprise recovery cost?
Firmware repair on atmospheric Exos models is $500-$800. Helium-sealed drive recovery is $800-$1,500 due to the added complexity. Multi-drive server RAID recovery ranges from $1,000-$2,000 depending on drive count and array type. If we recover no data, there is no charge.

Not a hard drive issue? We also recover SSDs, RAID arrays, and iPhones.
