SSD Controller Recovery
Samsung Pascal Controller Data Recovery
Samsung's Pascal is an 8nm, 8-channel NVMe Gen4 controller used in the 990 PRO. PC-3000 firmware-level FTL rebuilding is not available for Pascal. If the drive still enumerates, PC-3000 can force PCIe Gen1x1 speeds to stabilize the connection for extraction. If the controller is dead, recovery requires component-level voltage rail probing and PMIC microsoldering. PC-3000 SSD access for this controller is limited. Recovery starts at $200. No diagnostic fee.

Common Failure Modes and Symptoms
Each failure mode below describes a specific way the Samsung Pascal Controller fails and the symptoms you will observe. If your SSD matches any of these patterns, do not run recovery software; it cannot communicate with a dead controller. See why SSDs report 0 bytes for a deeper technical explanation of controller and FTL failures.
- Firmware panic / BSOD
Firmware panics cause the drive to drop offline, trigger BSODs, or fail to initialize. Because PC-3000 firmware-level FTL rebuilding is not available for Pascal, recovery relies on stabilizing the hardware through board-level repair.
- Drive not recognized in BIOS
- BSOD with 990 PRO installed
- Incorrect temperature readings
- Drive disappears randomly under load
- SMART health degradation bug
Early 990 PRO batches suffered from a firmware anomaly where the Pascal controller incorrectly calculates wear-leveling and NAND degradation. SMART health percentages drop at an impossible rate (10% within days with minimal writes). Once health reaches 0%, the controller enters read-only mode or BSY state from a corrupted defect mapping table.
- SMART health dropping rapidly with minimal writes
- Health percentage fell 10% or more in days
- Drive entered read-only mode prematurely
- Samsung Magician shows critical health warning
- Controller electrical failure
The Pascal controller or surrounding power management ICs fail electrically, preventing the drive from initializing. Because PC-3000 lacks firmware loaders for Pascal, recovery requires component-level microsoldering rather than software-based FTL reconstruction. If the Pascal IC itself has a dead short to ground, the data is unrecoverable.
- Drive completely dead, no enumeration in any system
- No response to PCIe bus queries
- No power draw or abnormal power draw measured at M.2 connector
- Drive does not appear in any USB enclosure or system
Samsung Pascal Controller Recovery Process
PC-3000 firmware-level FTL rebuilding is not available for Pascal. Recovery depends entirely on keeping or restoring the original Pascal IC. If the controller silicon has a dead short to ground, the AES-256 encryption key is permanently lost and the data is unrecoverable.
- Connect drive to PC-3000 Portable III via M.2 NVMe adapter
- If drive still enumerates: force PCIe link to Gen1x1 speeds via PC-3000 to stabilize the connection for extraction
- Perform sector-by-sector extraction with hardware read retries and custom timeout values
- If drive is in BSY state (dead): perform component-level diagnostics, probing 3.3V, 1.8V, and 1.2V voltage rails with a digital multimeter
- If PMIC is shorted: microsolder a replacement component to restore controller power delivery
- If Pascal IC has a dead short to ground: the AES-256 Media Encryption Key is lost and data is unrecoverable
Equipment Used
- PC-3000 Portable III
- FLIR thermal camera
- Hakko FM-2032 microsoldering iron
- digital multimeter

Transparent Pricing for NVMe Gen4 SSD Recovery
Flat-rate pricing with no diagnostic fees. The cost to recover data from a Samsung Pascal Controller-based SSD depends on the severity of the failure. For the full diagnostic path across controller, firmware, and NAND-level failures, see our SSD data recovery flagship; deleted-file cases are governed by DZAT and NAND physics. No data, no recovery fee. Full SSD recovery cost breakdown.
| Tier | What It Covers | Price |
|---|---|---|
| Simple Copy | Your NVMe drive works, you just need the data moved off it | $200 |
| File System Recovery | Your NVMe drive isn't showing up, but it's not physically damaged | From $250 |
| Circuit Board Repair | Your NVMe drive won't power on or has shorted components | $600–$900 |
| Firmware Recovery | Your NVMe drive is detected but shows the wrong name, wrong size, or no data | $900–$1,200 |
| PCB / NAND Swap | Your NVMe drive's circuit board is severely damaged and requires NAND chip transplant to a donor PCB | $1,200–$2,500 |
A donor drive is a matching SSD used for its circuit board. Typical donor cost: $40–$100 for common models, $150–$300 for discontinued or rare controllers. +$100 rush fee to move to the front of the queue.
