SanDisk Extreme/Extreme Pro Portable Data RecoverySanDisk Extreme Portable V2 (2TB, 4TB) / SanDisk Extreme Pro Portable (2TB, 4TB)
The SanDisk Extreme and Extreme Pro Portable SSDs have been subject to class-action lawsuits (filed August 2023) over sudden data loss. Root cause analysis by Attingo Data Recovery identified hardware design and manufacturing flaws, not firmware. Firmware revision R332G190 worsened reliability. We recover SanDisk Extreme/Extreme Pro Portable-based SSDs using our PC-3000 system's SanDisk-specific firmware tools at our Austin lab.

How We Recover SanDisk Extreme/Extreme Pro Portable SSDs
Firmware-Level Recovery
We recover SanDisk Extreme/Extreme Pro Portable-based SSDs using the PC-3000 SSD system with the SanDisk 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 SanDisk Extreme/Extreme Pro Portable failures, this is the primary recovery path.
Chip-Off Recovery
If the controller is dead and firmware-level access fails, we can desolder the NAND chips and read them directly. The SanDisk Extreme/Extreme Pro Portable uses a NAND encoding that our tools can reconstruct, making chip-off a viable last resort.
Can bypass failed controllers to access NAND. Chip-off viable as last resort.
Pricing
SSD firmware and logical recovery for the SanDisk Extreme/Extreme Pro Portable typically costs $300 to $500. Controller-level failures requiring advanced diagnostics are $500 to $1,500. Chip-off recovery, when viable, is $1,500 to $2,500.
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.
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.
