NVMe SSD Data Recovery

Why NVMe Drives Fail Differently Than SATA SSDs

SATA SSDs communicate through AHCI using ATA commands at speeds up to 600 MB/s. NVMe replaces this with a protocol designed for flash: up to 64,000 I/O queues, memory-mapped doorbell registers, and direct PCIe lane access at speeds exceeding 7,000 MB/s. This architectural difference creates three failure categories that SATA drives do not share.

NVMe Form Factors We Recover

NVMe drives come in several physical form factors. Each has different connector types, thermal characteristics, and access requirements during recovery.

M.2 2280

22mm wide, 80mm long. The standard NVMe form factor in desktops and laptops. Samsung 970/980/990 series, WD Black SN770/SN850X, Crucial P5 Plus, and most consumer NVMe drives use this size. The 4TB WD SN850X is double-sided, which causes fitment issues in single-sided M.2 slots.

M.2 2230

22mm wide, 30mm long. Found in Steam Deck, Microsoft Surface Pro, Dell XPS, and Framework laptops. Smaller PCB means denser component placement and tighter thermal margins. WD SN740, Micron 2400, and Samsung PM991a are common 2230 drives.

U.2 (2.5" NVMe)

Enterprise data center form factor using the SFF-8639 connector. Higher capacities (up to 30TB+), power loss protection capacitors, and dual-port PCIe for redundancy. Intel DC P4510, Samsung PM9A3, and Micron 9400 are common enterprise models.

PCIe Add-In Card (AIC)

Full-size PCIe cards used in workstations and servers. Intel Optane 905P and Samsung PM1733 are examples. These drives use x4 or x8 PCIe lanes and often have their own heatsinks, which reduces thermal failure risk compared to M.2 form factors.

Soldered NVMe (Apple MacBook)

Apple MacBooks with T2 or M-series chips have NAND soldered to the logic board, encrypted by the SoC's Secure Enclave. The NAND cannot be desoldered and read independently. Recovery requires board-level repair to restore the original logic board.

M.2 2242

22mm wide, 42mm long. Found in some industrial devices, thin clients, and embedded systems. Less common in consumer hardware but we handle them with the same NVMe diagnostic workflow.

PC-3000 NVMe Recovery Workflow

The PC-3000 Portable III acts as a PCIe Root Complex, managing memory mapping and doorbell signaling to communicate with NVMe controllers that have entered a fault state. Each controller family requires a vendor-specific diagnostic module.

1. 01

   Pre-Power Inspection

   FLIR thermal camera scans the drive for shorts before applying power. Voltage rails are tested individually with a bench power supply to isolate failed components. This prevents cascading damage from powering a shorted board.

2. 02

   Controller Identification

   Identify the NVMe controller die markings and NAND configuration. This determines which PC-3000 Active Utility to load: Samsung NVMe, Phison NVMe, Silicon Motion, or Universal NVMe for controllers without dedicated support (WD proprietary, Maxio).

3. 03

   Technological Mode Entry

   PC-3000 forces the controller into its vendor diagnostic mode (Technological Mode). In this mode, the controller bypasses its normal boot sequence and firmware validation, allowing direct access to NAND through the controller's hardware ECC and descrambling engines.

4. 04

   FTL Reconstruction

   If the Flash Translation Layer is corrupted, PC-3000 scans surviving FTL metadata spread across NAND pages to reconstruct the logical-to-physical block mapping. This process restores the drive's ability to present its file system to the OS.

5. 05

   Sector-by-Sector Imaging

   Once the controller responds, the entire drive is imaged sector-by-sector to a known-good destination drive. Bad sector maps are generated to track unreadable regions. Files are extracted, verified against directory structure, and returned on your choice of media.

Deleted File Recovery on NVMe Drives

NVMe implements the Deallocate command (the NVMe equivalent of SATA TRIM). When you delete a file, the operating system sends a Deallocate command to the controller, which marks those NAND blocks for garbage collection. On most NVMe implementations, garbage collection begins within seconds. Once the controller erases those NAND cells, the data is physically gone.

NVMe's Deallocate is more aggressive than SATA TRIM on most controller implementations. The combination of higher throughput and deeper I/O queues means the controller processes Deallocate commands faster, shrinking the forensic window for deleted data to near-zero on a functioning drive.
