Samsung Pablo Data RecoverySamsung 980 (non-PRO) / Samsung PM991/PM991a (OEM)
The Samsung Pablo is Samsung's first DRAM-less NVMe controller, used in the Samsung 980 (non-PRO). It relies on Host Memory Buffer (HMB) for FTL metadata caching, making it vulnerable to power-loss FTL corruption. The 4-channel Gen3 design pairs with Samsung V-NAND V6 (128-layer 3D TLC). We recover Samsung Pablo-based SSDs using our PC-3000 system's Samsung-specific firmware tools at our Austin lab.

Drives Using the Samsung Pablo
The following consumer SSDs use the Samsung Pablo. If your drive is on this list, the failure modes and recovery approaches described on this page apply to your situation.

Failure Modes
Each failure mode has a different root cause and requires a different recovery approach. Identifying the correct failure mode is the first step in any recovery.
HMB allocation failure
The DRAM-less Pablo controller relies on Host Memory Buffer for FTL metadata caching. If the host OS does not allocate HMB properly or system memory is constrained, FTL metadata can become inconsistent. Read performance drops to near zero, and the drive may time out or disappear from the system.
Symptoms you may notice
- Drive detected but read speeds near zero
- Timeout errors in Windows Event Viewer
- Drive disappears under memory pressure

Power loss FTL corruption
Without onboard DRAM, FTL metadata stored in NAND is vulnerable to corruption during unclean shutdowns. A single power loss event can corrupt the flash translation layer, causing the drive to report 0MB capacity or fail to enumerate.
Symptoms you may notice
- Drive not detected after power loss
- Shows 0MB in BIOS
- Drive fails to enumerate after outage

How We Recover Samsung Pablo SSDs
Firmware-Level Recovery
We recover Samsung Pablo-based SSDs using the PC-3000 SSD system with the Samsung Active Utility. This provides direct access to the controller's diagnostic interface for firmware repair and FTL (Flash Translation Layer) reconstruction.
Firmware-level access preserves the NAND chip layout and avoids the complications of chip-off recovery. For most Samsung Pablo failures, this is the primary recovery path.
Chip-Off Recovery
Chip-off is not viable for the Samsung Pablo due to hardware encryption or architectural limitations. Recovery depends on accessing the controller through firmware-level tools or manufacturer diagnostic modes.
AES-256 hardware encryption and proprietary NAND encoding make chip-off not viable. PC-3000 SSD Extended supports Samsung NVMe controllers. DRAM-less HMB design.
Pricing
SSD recovery for Samsung Pablo drives follows our published pricing: $200 for simple copies up to $1,200–$1,500 for complex component repair or advanced board rebuilds. File system recovery starts at $250. PCB repair is $600–$900. Firmware corruption is $900–$1,200. Free evaluation, firm quote before work begins.
See our full pricing breakdown for details. Our No Data, No Fee guarantee means you pay nothing if we cannot recover your files.
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 ULPA-filtered laminar-flow bench, validated to 0.02 µm particle count, verified using TSI P-Trak instrumentation.
Transparent History
Serving clients nationwide via mail-in service since 2008. Our lead engineer holds PC-3000 and HEX Akademia certifications for hard drive firmware repair and mechanical recovery.
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.
Technical Oversight
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.
